Mon Apr 16 13:25:52 UTC 2018
v2: add support for geometry shaders
set idx
add some missing mappings
fix for 64bit inputs/outputs
fix up some FP color output index messup
parse centroid flag
v3: fix arrays in outputs as well
fix input/ouput size calculation for tessellation shaders
v4: add getSlotAddress helper
fix for 64 bit typed inputs
v5: change getSlotAddress interface for easier use
fix sample inputs
fix slot counting for mat
v7: fix driver_location of images
