GL_ARB_enhanced_layouts, part 6: Numerical side of uniform offset and align semantics. Included
- moving offset calculations for std140/std430 from reflection to linkValidate.cpp - applying the offset/align rules on top of std140/std430 - removing caching the structure's number of components (and correcting that this is components, not size) git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@25174 e7fa87d3-cd2b-0410-9028-fcbf551c1848
