All icons in XorGramana have been created in the GIMP on a 256x256 
canvas. The icons are then flattened and scaled to 64x64 and exported to 
as RGB PNGs (Portable Network Graphics) file format.

In XorGramana, each different wall pattern has a corresponding floor 
pattern. If you want to design new additional textures there are 
#defines in icons.h and code in icons.c which need editing.

Many icons/sprites/textures/patterns/visuals in XorGramana have 
transparency. XorGramana uses black (rgb:0,0,0). Transparency is 
hard-coded from within icons.c.

Aswell as a floor pattern to accompany the wall pattern, you also need
four edge patterns to accompany the wall - one for each side. The edge
patterns are overlaid onto the wall pattern to form edged walls. The 
edge patterns use white (rgb:255,255,255) for the area to remain as the
original wall pattern. You can cut pieces out of the wall pattern by
painting the edge pattern black,or you could re-colour the edges of a 
wall pattern.

The edge patterns must also be 64x64 RGB PNG format.
