| This extension allows the fragment coverage value, represented as an integer |
| bitmask, to be substituted for a color output being written to a |
| single-component color attachment with integer components (e.g. |
| ename:VK_FORMAT_R8_UINT). |
| The functionality provided by this extension is different from simply |
| writing the code:SampleMask fragment shader output, in that the coverage |
| value written to the framebuffer is taken after stencil test and depth test, |
| as well as after fragment operations such as alpha-to-coverage. |
| |
| This functionality may be useful for deferred rendering algorithms, where |
| the second pass needs to know which samples belong to which original |
| fragments. |
