glsl: enable early_fragment_tests implicitly with post_depth_coverage
From ARB_post_depth_coverage: "This extension allows the fragment shader to control whether values in gl_SampleMaskIn[] reflect the coverage after application of the early depth and stencil tests. This feature can be enabled with the following layout qualifier in the fragment shader: layout(post_depth_coverage) in; Use of this feature implicitly enables early fragment tests." And a bit later it also adds: "early_fragment_tests" requests that fragment tests be performed before fragment shader execution, as described in section 15.2.4 "Early Fragment Tests" of the OpenGL Specification. If neither this nor post_depth_coverage are declared, per-fragment tests will be performed after fragment shader execution." Fixes: GL45-CTS.post_depth_coverage_tests.PostDepthSampleMask Reviewed-by: Marek Olšák <[email protected]>
