)

Sample attributes of current mesh (with UVs) to according images.

This function samples the specified attributes of the current bound mesh to their according attribute images. The mesh has to have a valid parameterization. When using OpenGL acceleration an OpenGL context has to be current. The function should preserve every state it changes of the current OpenGL context, so it may be called from anywhere in the program (except between glBegin()/glEnd() of course).
