* Make SkCodec more flexible about its required frameGravatar Leon Scroggins III2017-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkCodec sets fRequiredFrame to be the earliest possible frame that a given frame can depend on. e.g. - Frame A fills the screen, Keep - Frame B does not cover A, Keep - Frame C covers B but not A, and is opaque Frame C can depend on either A or B. SkCodec already reports that C depends on A. This CL allows a client of SkCodec to use either A or B to create C. Also expose the DisposalMethod. Since any frame between A and C can be used to create C except for DisposePrevious frames, the client needs to be able to know the disposal method so they do not try to use such a frame to create C. Further, the disposal method can be used to give the client a better idea whether they will continue to need a frame. (e.g. if frame i is DisposePrevious and depends on i-1, the client may not want to steal i-1 to create i, since i+1 may also depend on i-1.)

* disable coverage optimization for hairlinesGravatar Mike Reed2017-06-07
| | | | | | | | | | | | | The coverage blitter is an optimization of regular blitting to A8. It can go faster because it never tries to blend with itself... because it was intended to be called only by fill-path, which is written to never draw twice in the same place. Hairlines don't make this promise, so we can use the coverage optimization for hairlines.

* GrTessellator: implement out-of-range splitting and AEL rewinding.Gravatar Stephen White2017-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to floating point inaccuracy, when intersecting edges, the intersection point may fall above one of the edges' top vertices or below one of the bottom vertices. In these cases, we were simply splitting one edge on the relevant endpoint of the other edge. This is incorrect if the intersection is far from the endpoint (e.g., the test case in the linked bug, where one of the intersected edges is near-horizontal but the intersection falls below both of its endpoints, in the middle of the edge.) The correct solution is to split both edges as normal, and take care to produce edges with the correct ordering where the intersection is above or below an edge. However, since the new vertex may be above the current vertex, simply restarting intersection checks at the current vertex won't work. We need to process the intersection vertex before the current one. This introduces another problem: unlike all other splitting modes (which always shorten edges), splitting an edge above the top or below the bottom can lengthen it, causing it to violate the AEL with an adjacent edge which then shortens it back to the original point (in cleanup_active_edges()). Since the splitting and merging code can't agree, we loop forever. Instead of simply fusing neighboring edges in cleanup_active_edges(), the proper fix to this problem is to detect the AEL violation and rewind all processing to the vertex above it. For performance, we only rewind when we detect that a split edge is no longer ordered within the mesh (merge_enclosing_edges()) or within the the AEL (rewind_if_necessary()). We also store the enclosing edges of each vertex, which allows us to rewind quickly, since we know exactly which edges need to be added/removed from the AEL. cleanup_active_edges(), fix_active_state() and Vertex::fProcessed have been removed. In their place are rewind_active_edges() and rewind_if_necessary(), which uses the same logic as cleanup_active_edges() but uses it to know when to rewind.
