*	Use noperspective interpolation for 2D draws	cdalton	2016-02-12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Adds a mechanism to notify GrGLSLVaryingHandler that a shader will not emit geometry in perspective. This gives it a chance to use the noperspective keyword if it is supported. Updates the existing processors to notify the varying handler when there is no perspective. Begins using the noperspective keyword in GrGLGpu internal shaders. Web scenes with observable benefit (Pixel C, gpu config): tabl_nofolo.skp 4.62 -> 3.33 ms 28% desk_tigersvg.skp 26.5 -> 24 ms 9% desk_pokemonwiki.skp 16.1 -> 14.9 ms 7% tabl_deviantart.skp 3.97 -> 3.7 ms 7% desk_gws.skp 3.85 -> 3.65 ms 5% Also adds new methods for creating varyings with flat interpolation.
