+    // rectangular matrix, from top to bottom or from bottom to top depending 
+    // on stride.

+    // row_accessor is cheap to create/destroy, but performs one multiplication
+    // when calling row_ptr().
+    // 
+    // row_ptr_cache creates an array of pointers to rows, so, the access 
+    // via row_ptr() may be faster. But it requires memory allocation 
+    // when creating. For example, on typical Intel Pentium hardware 
+    // row_ptr_cache speeds span_image_filter_rgb_nn up to 10%
+    //
+    // It's used only in short hand typedefs like pixfmt_rgba32 and can be 
+    // redefined in agg_config.h
+    // In real applications you can use both, depending on your needs
