| // RedefineInterfaceBlockLayoutQualifiersWithStd: Change the memory layout qualifier of interface |
| // blocks if not specifically requested to be std140 or std430, i.e. the memory layout qualifier is |
| // changed if it's unspecified, shared or packed. This makes the layout qualifiers conformant with |
| // Vulkan GLSL (GL_KHR_vulkan_glsl). |
| // |
| // - For uniform buffers, std140 is used. It would have been more efficient to default to std430, |
| // but that would require GL_EXT_scalar_block_layout. |
| // - For storage buffers, std430 is used. |
