19    Multisample framebuffer object tests
20
21Tests:
22 + dEQP-GLES3.functional.fbo.msaa.*
23
24Includes:
25 + Creating framebuffer objects with multisample color, depth and stencil buffers
26 + All specification-mandated color, depth and stencil formats
27 + Basic rendering to MSAA framebuffer objects
28 + Minimum of 1, 4 and 8 samples
29 + Multisample resolve in glBlitFramebuffer()
30
31Excludes:
32 + Coverage value computation in primitive rasterization
33   - Will be covered in primitive rasterization test set (2012.2)
34
35Description:
36
37Each test case exercises a combination of sample count and color, depth
38and stencil renderbuffer formats. Simple scene is rendered to the framebuffer
39object in such way that all allocated buffers will be exercised. Multisampled
40colorbuffer contents are then resolved to non-multisampled renderbuffer
41using glBlitFramebuffer() and read from there using glReadPixels().
42
43Resulting image is compared agaist an image produced by a reference renderer.
