Changes here is the gaussian, morph, and border mask filters all have identical vertex stages so they can share them now.
Likewise, vertices_uber and porter duff have identical vertex stages.
Also we don't need two gaussians, only ever need one.

Everything thing looks good. I think now that we have this setup as an example it will hopefully reduce future pipeline bloat.
We should keep the kernel.glsl filename though to promote shader resuse. Renaming all of the typedefs Kernel->Gaussian sounds good to me though.

We should keep the name of this file as kernel.glsl since our goal is to minimize the number of shaders and this shader isn't specific to gaussian blur.

i'd argue we could pursue that if we have a use for that, but until then YAGNI

There's nothing to pursue, it's already in a good state, just undo the changes =) Had we named our shaders based on what they do versus what they are used for in the past we may not have had to do all this cleanup now.

Its only used for a gaussian blur, the name is more correct

Reduces shader count slightly, and reduces duplication of source code for vertex stages that are identical.
