Updates texture information used by the viewport display system.

It extracts mapping channel and texture transform information from the provided Texmap. Client code needs to call this method in its implementation of ITextureDisplay::SetupTextures() for each texture map of a material or sub-texture of a texture map plug-in.

Parameters:

t	The time at which the texture information is updated.
mapUsage	The map usage which specifies which of the internal texture information will be updated.
texMap	The texture map representing the source for the texture information update.
