Proposed solution for 1.5:
Move notex.tga and shadernotex.tga into a fixed location relative to AppPath, 
and ensure that they are always installed when the app is installed.
eg. ./bitmaps/notex.bmp and ./bitmaps/shadernotex.bmp
These images are special cases, they are never loaded by anything else, so they 
don't have to be under a VFS path.
They are required when editing any game that uses the shaders module - 
they "belong" to the shaders module.
