Summary: Textures should use packed pixel extension

Initial Comment:
We currently convert all incoming textures to 32bpp RGBA for 
passing to OpenGL - most OpenGL implementations will now 
support the packed pixel extension, so we should be able to pass 
on 16 or 24 bit pixel data directly rather than copying it.
        
This could also simplify the texture swapping code in IRUpdate.c, 
which  is quite complex and a bit misleading (e.g., 16bpp texture 
data is not really swapped, it's permuted, and yet the variable is 
called 'swap').
