/*
* XPM (X PixMap) image loader:
*
* Supports the XPMv3 format, EXCEPT:
* - hotspot coordinates are ignored
* - only colour ('c') colour symbols are used
* - rgb.txt is not used (for portability), so only RGB colours
* are recognized (#rrggbb etc) - only a few basic colour names are
* handled
*
* The result is an 8bpp indexed surface if possible, otherwise 32bpp.
* The colourkey is correctly set if transparency is used.
*
* Besides the standard API, also provides
*
* SDL_Surface *IMG_ReadXPMFromArray(char **xpm)
* SDL_Surface *IMG_ReadXPMFromArrayToRGB888(char **xpm)
*
* that read the image data from an XPM file included in the C source.
* - 1st function returns an 8bpp indexed surface if possible, otherwise 32bpp.
* - 2nd function returns always a 32bpp (RGB888) surface
*
* TODO: include rgb.txt here. The full table (from solaris 2.6) only
* requires about 13K in binary form.
