* Separate creation time & flush time behavior in GrDrawOpAtlasGravatar Robert Phillips2018-02-21
| | | | | | | | | | | | | | | | | | | | | | | | This CL clarifies what is going on in the GrDrawOpAtlas and GrAtlasGlyphCache. For the GrDrawOpAtlas: At creation time all the allowed pages are created (with their backing GrTextureProxies) but they aren't instantiated. The GrDrawOpAtlas::instantiate call is called in preFlushCB and allocates any pages known to be needed at the start of flush GrDrawOpAtlas::addToAtlas is called at flush time and, if a new page is activated, will instantiated it at that time. During compaction, an unused page will be deInstantiated but its Plots and backing GrTextureProxy will remain alive. The GrAtlasGlyphCache reflects the changes to the GrDrawOpAtlas It now carries a GrProxyProvider for when it needs to create an atlas It passes in a GrResourceProvider* at flush time to allow instantiation. It does not, yet, allocate that GrDrawOpAtlases it might ever require.

* Introduce GrColorTypeGravatar Brian Salomon2018-02-20
| | | | | | | | | | | | | | | | | | This begins the journey towards using different types to refer to CPU data and GPU texture formats. This is one part of removing GrPixelConfig and more directly using GL/VK texture formats GrColorType represents a particular layout of color/gray/alpha channels in CPU memory. It does not refer to texture formats or sRGB-encoding. It is basically SkColorType specialized to the GPU backend with some formats added and some removed. Read/WritePixel interfaces use GrColorType to describe the CPU side of the transaction. There's still a lot of punting to GrPixelConfig in API-specific code. There's a lot more to be done.

* Avoid creating MIPs until necessary when MIP bias is activeGravatar Brian Osman2018-02-16
| | | | | | | | | | | | With sharpened mips, the scale at which we begin to sample level 1 is (obviously) less than 1. This change avoids creation of mips for images that are only slightly downscaled (and for which we wouldn't have sampled those MIPs anyway).
