Revert "Redefine the meaning of sample counts in GPU backend."
This reverts commit 48825b11ad25c98b9a4884d5cc0edd4e290c4409. Reason for revert: nanobench Original change's description: > Redefine the meaning of sample counts in GPU backend. > > Old: 0 -> nonMSAA > 1+ -> MSAA > > New: > 0 -> error/unsupported > 1 -> nonMSAA > 2+ -> MSAA > > We still allow 0 to mean nonMSAA in three sets of public APIs for backwards compatibility: > > 1) SkSurface factories > 2) GrBackendRenderTarget constructors > 3) GrCaps::getSampleCnt()'s requestedCount parameter > > However, we immediately clamp to 1 and treat 0 as invalid/non-renderable internally. > > This also changes the behavior when using a large sample count. We now fail in that case rather than using the largest sample available sample count. GrCaps::getSampleCount() will return 0 in this case. > > > Bug: skia: > Change-Id: Ida22c6b22c1365e563c9046b611e88bf5eb3ff33 > Reviewed-on: https://skia-review.googlesource.com/101560 > Reviewed-by: Greg Daniel <egdaniel@google.com> > Commit-Queue: Brian Salomon <bsalomon@google.com> TBR=egdaniel@google.com,bsalomon@google.com Change-Id: Ic257619a8a5ee9ac15419ecf10259e42daed7f82 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: skia: Reviewed-on: https://skia-review.googlesource.com/102662 Reviewed-by: Brian Salomon <bsalomon@google.com> Commit-Queue: Brian Salomon <bsalomon@google.com>
