Revert "Alloc glyph image correctly for SkMask::k3D_Format."
This reverts commit 1662257bdaaaf26b016bf2a3e329c34f7f5ed581. Reason for revert: Android still using this API Original change's description: > Alloc glyph image correctly for SkMask::k3D_Format. > > Remove the no longer used outside Skia SK_SUPPORT_LEGACY_EMBOSSMASKFILTER > define, and either delete the code it guards or update it to use the new > emboss mask filter factory. > > Re-enable the code to test the emboss mask filter. > > Add a test to ensure that embossed text is drawn correctly, as before > glyphs did not allocate the proper amount of memory for the k3D_Format > which the emboss mask filter produces. > > Fixes SkEmbossMask::Emboss to write the whole of the mul and add planes > to avoid pixel differences and MemorySanitizer errors. > > Update the GPU to understand the k3D_Format and use just the alpha > plane, ignoring the mul and add plane which it currently cannot support. > > Change-Id: Icac1a3f37d6e8c6be3151df570f5e14111e18585 > Reviewed-on: https://skia-review.googlesource.com/70260 > Reviewed-by: Herb Derby <herb@google.com> > Reviewed-on: https://skia-review.googlesource.com/70962 > Commit-Queue: Ben Wagner <bungeman@google.com> TBR=djsollen@google.com,bungeman@google.com,herb@google.com Change-Id: Id6625bae8d3bd70ce7aa3045348c04fdd146c637 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://skia-review.googlesource.com/71183 Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: Brian Osman <brianosman@google.com>
