SHADERS
When not explicity specifying what texture target to use, OF uses GL_TEXTURE_RECTANGLE_ARB by default.
This results in shaders having to use sampler2DRect for the texture type and real texture coordinates.
By calling ofDisableArbTex() texture targets are switched to GL_TEXTURE_2D.
This results in shaders having to use sampler2D as texture type and Normalized coordinates.
