* Avoid re-rendering stencil clip for every draw with reducable clip stackGravatar commit-bot@chromium.org2013-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes the cases where clip stack reduction would cause clip to be re-rendered to stencil for each draw call. This causes unneeded slowdown. Stencil cache would not be used because the clip stack generation id communicated by the clip stack element list would be invalid. This happended due to a) clip stack reduction creating new elements in the element list. b) purging logic removing the generation id, but reduction logic selecting already purged element, and thus the generation id, as the representative state of the clip. Cases of a) where reduction would flatten the stack to a single new element were fixed by assigning the generation id of the top-most element of the clip stack as the generation id of the new element. This is not strictly minimal, but enables more caching than using invalid id. Cases of a) where reduction would substitute a stack element with a new element the generation id of the substituted element is used. The b) part was fixed by removing the purging logic. It was not exactly correct, as the previously purged states were actually used. The purging was not used for anything. Changes SkClipStack API to highlight that invalid generation id is never returned by SkClipStack. Empty stacks are wide open. Changes the clients to reflect this. Fixes a crash when not passing anti-alias out parameter to GrReducedClip::ReduceClipStack. The crash is not exercised in the current code.
