Description Lionel Landwerlin 2016-06-06 20:40:54 UTC 
I'm trying to port Cogl to Vulkan and made some good progress with several examples running.
The one I'm struggling a bit with is using gl_PointSize. It hangs my HSW GPU reliably.
Attached are the shaders in GLSL and SPIRV format (as generated by glslang).
