+ wxPixelFormat is a template class describing the bitmap data format. It
+ contains the constants describing the format of pixel data, but does not
+ describe how the entire bitmap is stored (i.e. top-to-bottom,
+ bottom-to-top, ...). It is also a "traits"-like class, i.e. it only
+ contains some constants and maybe static methods but nothing more, so it
+ can be safely used without incurring any overhead as all accesses to it are
+ done at compile-time.
+
+ Current limitations: we don't support RAGABA and ARAGAB formats supported
+ by Mac OS X. If there is sufficient interest, these classes could be
+ extended to deal with them. Neither do we support alpha channel having
+ different representation from the RGB ones (happens under QNX/Photon I
+ think), but again this could be achieved with some small extra effort.
+
+ Template parameters are:
+ - type of a single pixel component
+ - size of the single pixel in bits
+ - indices of red, green and blue pixel components inside the pixel
+ - index of the alpha component or -1 if none
+ - type which can contain the full pixel value (all channels)
