Implement access chain flattening support for row major matrices We currently only support access chains that end in a matrix by propagating "needs transpose" flag upstream which flips the matrix multiplication order. It's possible to support indexed extraction as well, however it would have to generate code like this: vec4 row = vec4(UBO[0].y, UBO[1].y, UBO[2].y, UBO[3].y); for a column equivalent of: vec4 row = UBO[1]; It is definitely possible to do so but it requires signaling the vector output that it needs to switch to per-component extraction which is a bit more trouble than this is worth for now. 2017-01-18 02:10:28 +00:00			`#version 310 es`

Add explicit in/out locations everywhere. Needed for newer glslang. With Vulkan semantics for SPIR-V, all locations must be explicitly defined. 2017-06-21 07:39:08 +00:00			`layout(location = 0) in vec4 aVertex;`
