-NOTE TTimo: there is an important distinction between SHADER_NOT_FOUND and SHADER_NOTEX:
-SHADER_NOT_FOUND means we didn't find the raw texture or the shader for this
-SHADER_NOTEX means we recognize this as a shader script, but we are missing the texture to represent it
-this was in the initial design of the shader code since early GtkRadiant alpha, and got sort of foxed in 1.2 and put back in
