+// http://incubator.quasimondo.com/processing/fast_blur_deluxe.php
+// (search phrase "Stackblur: Fast But Goodlooking"). 
+// The major improvement is that there's no more division table
+// that was very expensive to create for large blur radii. Insted, 
+// for 8-bit per channel and radius not exceeding 254 the division is 
+// replaced by multiplication and shift.

+// This file can be used to redefine certain data types.
+
+//---------------------------------------
+// 1. Default basic types such as:
+// 
+// AGG_INT8
+// AGG_INT8U
+// AGG_INT16
+// AGG_INT16U
+// AGG_INT32
+// AGG_INT32U
+// AGG_INT64
+// AGG_INT64U
+//
+// Just replace this file with new defines if necessary. 
+// For example, if your compiler doesn't have a 64 bit integer type
+// you can still use AGG if you define the follows:
+//
+// #define AGG_INT64  int
+// #define AGG_INT64U unsigned
+//
+// It will result in overflow in 16 bit-per-component image/pattern resampling
+// but it won't result any crash and the rest of the library will remain 
+// fully functional.
+
+
+//---------------------------------------
+// 2. Default rendering_buffer type. Can be:
+//
+// Provides faster access for massive pixel operations, 
+// such as blur, image filtering:
+// #define AGG_RENDERING_BUFFER row_ptr_cache<int8u>
+// 
+// Provides cheaper creation and destruction (no mem allocs):
+// #define AGG_RENDERING_BUFFER row_accessor<int8u>
+//
+// You can still use both of them simultaneously in your applications 
+// This #define is used only for default rendering_buffer type,
+// in short hand typedefs like pixfmt_rgba32.

+    // and curve4. Curve3 is a conic Bezier curve with 2 endpoints and 1 control
+    // point. Curve4 has 2 control points (4 points in total) and can be used
+    // to interpolate more complicated curves. Curve4, unlike curve3 can be used 
+    // to approximate arcs, both circular and elliptical. Curves are approximated 
+    // with straight lines and one of the approaches is just to store the whole 
+    // sequence of vertices that approximate our curve. It takes additional 
+    // memory, and at the same time the consecutive vertices can be calculated 
+    // on demand.

+    // keeps only vertices, needed to calculate a curve on demand. Those vertices
+    // are marked with special commands. So, if the path_storage contains curves 
+    // (which are not real curves yet), and we render this storage directly, 
+    // all we will see is only 2 or 3 straight line segments (for curve3 and

+    //==================================================rasterizer_scanline_aa
+    // Polygon rasterizer that is used to render filled polygons with 
+    // high-quality Anti-Aliasing. Internally, by default, the class uses 
+    // integer coordinates in format 24.8, i.e. 24 bits for integer part 
+    // and 8 bits for fractional - see poly_subpixel_shift. This class can be 
+    // used in the following  way:
+    //
+    // 1. filling_rule(filling_rule_e ft) - optional.
+    //
+    // 2. gamma() - optional.
+    //
+    // 3. reset()
+    //
+    // 4. move_to(x, y) / line_to(x, y) - make the polygon. One can create 
+    //    more than one contour, but each contour must consist of at least 3
+    //    vertices, i.e. move_to(x1, y1); line_to(x2, y2); line_to(x3, y3);
+    //    is the absolute minimum of vertices that define a triangle.
+    //    The algorithm does not check either the number of vertices nor
+    //    coincidence of their coordinates, but in the worst case it just 
+    //    won't draw anything.
+    //    The orger of the vertices (clockwise or counterclockwise) 
+    //    is important when using the non-zero filling rule (fill_non_zero).
+    //    In this case the vertex order of all the contours must be the same
+    //    if you want your intersecting polygons to be without "holes".
+    //    You actually can use different vertices order. If the contours do not 
+    //    intersect each other the order is not important anyway. If they do, 
+    //    contours with the same vertex order will be rendered without "holes" 
+    //    while the intersecting contours with different orders will have "holes".
+    //
+    // filling_rule() and gamma() can be called anytime before "sweeping".

+    //==================================================rasterizer_scanline_aa_nogamma
+    // Polygon rasterizer that is used to render filled polygons with 
+    // high-quality Anti-Aliasing. Internally, by default, the class uses 
+    // integer coordinates in format 24.8, i.e. 24 bits for integer part 
+    // and 8 bits for fractional - see poly_subpixel_shift. This class can be 
+    // used in the following  way:
+    //
+    // 1. filling_rule(filling_rule_e ft) - optional.
+    //
+    // 2. gamma() - optional.
+    //
+    // 3. reset()
+    //
+    // 4. move_to(x, y) / line_to(x, y) - make the polygon. One can create 
+    //    more than one contour, but each contour must consist of at least 3
+    //    vertices, i.e. move_to(x1, y1); line_to(x2, y2); line_to(x3, y3);
+    //    is the absolute minimum of vertices that define a triangle.
+    //    The algorithm does not check either the number of vertices nor
+    //    coincidence of their coordinates, but in the worst case it just 
+    //    won't draw anything.
+    //    The orger of the vertices (clockwise or counterclockwise) 
+    //    is important when using the non-zero filling rule (fill_non_zero).
+    //    In this case the vertex order of all the contours must be the same
+    //    if you want your intersecting polygons to be without "holes".
+    //    You actually can use different vertices order. If the contours do not 
+    //    intersect each other the order is not important anyway. If they do, 
+    //    contours with the same vertex order will be rendered without "holes" 
+    //    while the intersecting contours with different orders will have "holes".
+    //
+    // filling_rule() and gamma() can be called anytime before "sweeping".

+    // Unpacked scanline container class
+    //
+    // This class is used to transfer data from a scanline rasterizer 
+    // to the rendering buffer. It's organized very simple. The class stores 
+    // information of horizontal spans to render it into a pixel-map buffer. 
+    // Each span has staring X, length, and an array of bytes that determine the 
+    // cover-values for each pixel. 
+    // Before using this class you should know the minimal and maximal pixel 
+    // coordinates of your scanline. The protocol of using is:
+    // 1. reset(min_x, max_x)
+    // 2. add_cell() / add_span() - accumulate scanline. 
+    //    When forming one scanline the next X coordinate must be always greater
+    //    than the last stored one, i.e. it works only with ordered coordinates.
+    // 3. Call finalize(y) and render the scanline.
+    // 3. Call reset_spans() to prepare for the new scanline.
+    //    
+    // 4. Rendering:
+    // 
+    // Scanline provides an iterator class that allows you to extract
+    // the spans and the cover values for each pixel. Be aware that clipping
+    // has not been done yet, so you should perform it yourself.
+    // Use scanline_u8::iterator to render spans:

+    // Affine transformation are linear transformations in Cartesian coordinates
+    // (strictly speaking not only in Cartesian, but for the beginning we will 
+    // think so). They are rotation, scaling, translation and skewing.  
+    // After any affine transformation a line segment remains a line segment 
+    // and it will never become a curve. 
+    //
+    // There will be no math about matrix calculations, since it has been 
+    // described many times. Ask yourself a very simple question:
+    // "why do we need to understand and use some matrix stuff instead of just 
+    // rotating, scaling and so on". The answers are:
+    //
+    // 1. Any combination of transformations can be done by only 4 multiplications
+    //    and 4 additions in floating point.
+    // 2. One matrix transformation is equivalent to the number of consecutive
+    //    discrete transformations, i.e. the matrix "accumulates" all transformations 
+    //    in the order of their settings. Suppose we have 4 transformations: 
+    //       * rotate by 30 degrees,
+    //       * scale X to 2.0, 
+    //       * scale Y to 1.5, 
+    //       * move to (100, 100). 
+    //    The result will depend on the order of these transformations, 
+    //    and the advantage of matrix is that the sequence of discret calls:
+    //    rotate(30), scaleX(2.0), scaleY(1.5), move(100,100) 
+    //    will have exactly the same result as the following matrix transformations:
+    //   
+    //    affine_matrix m;
+    //    m *= rotate_matrix(30); 
+    //    m *= scaleX_matrix(2.0);
+    //    m *= scaleY_matrix(1.5);
+    //    m *= move_matrix(100,100);
+    //
+    //    m.transform_my_point_at_last(x, y);
+    //
+    // What is the good of it? In real life we will set-up the matrix only once
+    // and then transform many points, let alone the convenience to set any 
+    // combination of transformations.
+    //
+    // So, how to use it? Very easy - literally as it's shown above. Not quite,
+    // let us write a correct example:
+    //
+    // agg::trans_affine m;
+    // m *= agg::trans_affine_rotation(30.0 * 3.1415926 / 180.0);
+    // m *= agg::trans_affine_scaling(2.0, 1.5);
+    // m *= agg::trans_affine_translation(100.0, 100.0);
+    // m.transform(&x, &y);
+    //
+    // The affine matrix is all you need to perform any linear transformation,
+    // but all transformations have origin point (0,0). It means that we need to 
+    // use 2 translations if we want to rotate someting around (100,100):
+    // 
+    // m *= agg::trans_affine_translation(-100.0, -100.0);         // move to (0,0)
+    // m *= agg::trans_affine_rotation(30.0 * 3.1415926 / 180.0);  // rotate
+    // m *= agg::trans_affine_translation(100.0, 100.0);           // move back to (100,100)

+// class platform_support
+//
+// It's not a part of the AGG library, it's just a helper class to create 
+// interactive demo examples. Since the examples should not be too complex
+// this class is provided to support some very basic interactive graphical
+// functionality, such as putting the rendered image to the window, simple 
+// keyboard and mouse input, window resizing, setting the window title,
+// and catching the "idle" events.
+// 
+// The idea is to have a single header file that does not depend on any 
+// platform (I hate these endless #ifdef/#elif/#elif.../#endif) and a number
+// of different implementations depending on the concrete platform. 
+// The most popular platforms are:
+//
+// Windows-32 API
+// X-Window API
+// SDL library (see http://www.libsdl.org/)
+// MacOS C/C++ API
+// 
+// This file does not include any system dependent .h files such as
+// windows.h or X11.h, so, your demo applications do not depend on the
+// platform. The only file that can #include system dependend headers
+// is the implementation file agg_platform_support.cpp. Different
+// implementations are placed in different directories, such as
+// ~/agg/src/platform/win32
+// ~/agg/src/platform/sdl
+// ~/agg/src/platform/X11
+// and so on.
+//
+// All the system dependent stuff sits in the platform_specific 
+// class which is forward-declared here but not defined. 
+// The platform_support class has just a pointer to it and it's 
+// the responsibility of the implementation to create/delete it.
+// This class being defined in the implementation file can have 
+// any platform dependent stuff such as HWND, X11 Window and so on.

+    // would have no overhead for pixel format conersion. 
+    // But eventually I came to a conclusion that having a possibility to 
+    // convert pixel formats on demand is a good idea. First, it was X11 where 
+    // there lots of different formats and visuals and it would be great to 
+    // render everything in, say, RGB-24 and display it automatically without
+    // any additional efforts. The second reason is to have a possibility to 
+    // debug renderers for different pixel formats and colorspaces having only 
+    // one computer and one system.

+    // rendering files without having to modify any existing ones (a general 
+    // principle of incapsulation and isolation).
+    //

+    //
+    // By Eric Haines, 3D/Eye Inc, erich@eye.com
+    //
+    // This version is usually somewhat faster than the original published in
+    // Graphics Gems IV; by turning the division for testing the X axis crossing
+    // into a tricky multiplication test this part of the test became faster,
+    // which had the additional effect of making the test for "both to left or
+    // both to right" a bit slower for triangles than simply computing the
+    // intersection each time.  The main increase is in triangle testing speed,
+    // which was about 15% faster; all other polygon complexities were pretty much
+    // the same as before.  On machines where division is very expensive (not the
+    // case on the HP 9000 series on which I tested) this test should be much
+    // faster overall than the old code.  Your mileage may (in fact, will) vary,
+    // depending on the machine and the test data, but in general I believe this
+    // code is both shorter and faster.  This test was inspired by unpublished
+    // Graphics Gems submitted by Joseph Samosky and Mark Haigh-Hutchinson.
+    // Related work by Samosky is in:
+    //
+    // Samosky, Joseph, "SectionView: A system for interactively specifying and
+    // visualizing sections through three-dimensional medical image data",
+    // M.S. Thesis, Department of Electrical Engineering and Computer Science,
+    // Massachusetts Institute of Technology, 1993.
+    //
+    // Shoot a test ray along +X axis.  The strategy is to compare vertex Y values
+    // to the testing point's Y and quickly discard edges which are entirely to one
+    // side of the test ray.  Note that CONVEX and WINDING code can be added as
+    // for the CrossingsTest() code; it is left out here for clarity.
+    //

+    // _point_, returns 1 if inside, 0 if outside.
