Chris Healy 6dae3327a6 GPU: Remove dead helper functions from fragment shader 
Remove two unused helper functions that were left behind after refactoring:

1. unpackUVec3: Left over from commit 4329aaa31c ("GPU: Apply color
   test mask as a uint") which refactored color test to use
   roundAndScaleTo8x4 with direct uint comparison instead of unpacking
   to uvec3 components.

2. packFloatsTo8x4: Left over from commit aec22491fe ("Don't expand
   alphaColorRef to 128 bytes") which changed u_alphacolorref from vec4
   to uint, making the float-to-uint packing function unnecessary.

Both functions were defined but never called, wasting shader compilation
time and binary size for shaders that enable color testing.

Henrik Rydgård 6e0ec4a131 Slightly nudge down the multiplier used for float->u8 conversion in fragment shaders 
Seems in lowp precision (as seen on some Android devices) this got
rounded up to 256 when multiplied by 1.0, causing the u8 to overflow, giving
us the wrong value instead of nicely rounding down to 255 with the floor
function.

Henrik Rydgård 69b43ab734 Extend the Test Drive color ramp smoother to detect up to 3 ramps in a texture. 
Note that we also offset the lookup slightly to miss the wrap-around
points. The existing 31 scale factor instead of 32, together with that
half-texel, are enough to avoid that problem.

Henrik Rydgård 6d8069dfd1 Vulkan: Remove the remains of the input attachment experiment 
Haven't been using these for a while.

I've come to the conclusion here that I think it's better to try to
deal with the issues using safe workarounds like copies, instead of
relying on features with somewhat iffy driver support that are not
universal across APIs anyway.

Will resolve a future issue in the multisampling PR, where the
GPU_USE_FRAMEBUFFER_FETCH flag changes at runtime if you switch between no AA and MSAA.

Just figured I'd get it in separately for safety.
