Martin Gräßlin a05ad98896 Remove textureWidth/textureHeight from all Shaders The uniforms textureWidth and textureHeight were only needed for normal windows. For everything else it was just 1.0/1.0, that is normalized. The makeArrays method is changed to produce normalized texcoords obsoleting the need for these uniforms. So two uniforms less, one calculation in vertex shaders less and many many lines of code removed. At the same time makeArrays is also adjusted to take care of yInverted of the texture, which is needed as we no longer can use the enableUnnormalizedTexCoords which did the yInverted transformation.

Martin Gräßlin a05ad98896 Remove textureWidth/textureHeight from all Shaders

The uniforms textureWidth and textureHeight were only needed for
normal windows. For everything else it was just 1.0/1.0, that is
normalized.

The makeArrays method is changed to produce normalized texcoords
obsoleting the need for these uniforms. So two uniforms less, one
calculation in vertex shaders less and many many lines of code
removed.

At the same time makeArrays is also adjusted to take care of
yInverted of the texture, which is needed as we no longer can use
the enableUnnormalizedTexCoords which did the yInverted transformation.
