llvmpipe: 1x1 framebuffer with a 2x2 viewport
dEQP-GLES31.functional.fbo.no_attachments.npot_size.1x1
runs a test where is sets the FBO no attachment size to 1x1 and sets the viewport to 2x2.
However llvmpipe the generates 2 triangles that fill a 4x4 quad, but nothing ever scissors those rects to the fbo size.
The test checks the result of an occlusion query to see if something gets rendered after a discard and fails. I'm just looking for some idea if this is just a missing case due no attachments, and previous llvmpipe didn't care and if so where I should be fixing it.
@sroland you might answer this best.
