Adding monitoring for (approximate) VRAM used by textures. The information is currently only used in the profiling data of the BGE.
Here is a image of it in action: http://www.pasteall.org/pic/show.php?id=6351 What it monitors: * VRAM used by textures created via bf_gpu and BL_Textures What it does not monitor: * VRAM used by the Blender ui * VRAM used by 2d filters * VRAM allocated by the user via KX_Scene.pre_draw and KX_Scene.pre_draw
