/*

* 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)

*

* that reads the image data from an XPM file included in the C source.

*

* TODO: include rgb.txt here. The full table (from solaris 2.6) only

* requires about 13K in binary form.
