virtual void remap_texture(csTextureManager* new_palette)

Remap the texture in the best possible way. The default implementation will switch only between 16Bit and 32Bit modes. That is simple, but enough for OpenGL and DirectX. Other renderers will have to override this method for appropriate results.

virtual void remap_palette_24bit(csTextureManager* new_palette)

This function does not really remap but it converts the format to an ULong format suitable for 24-bit internal texture format

virtual void remap_texture_16(csTextureManager* new_palette)

Remap the 2d texture to 16-bit display format

virtual void remap_texture_32(csTextureManager* new_palette)

Remap the 2d texture to 32-bit display format
