* | Use path intersection instead of saveLayer+mesh to mask projected ripplesChris Craik2015-05-261-2/+51
|/ | | | | | | | | | | | | | | | | | | | | bug:14297149 SaveLayer's performance cost is high, and proportional to the surface being projected onto. Since ripples (even unbounded ones) are now always projected to the arbitrary background content behind them, this cost is especially important to avoid. This removes the last semi-secret, saveLayer from the projected ripple implementation. Also fixes the HW test app to correctly demonstrate this projection masking behavior. Additionaly, alters PathTessellator to gracefully handle counter-clockwise paths, and simplifies the work done by ShadowTessellator to ensure all of its paths are counterclockwise.

* Clean up quick rejection, especially surrounding points + lines.Chris Craik2013-11-221-10/+28
| | | | | | | | | | | | | | | | | | | | bug:4351353 quickReject and quickRejectNoScissor have been renamed and refactored: - to make the scissor side effect clear and explicit - dangerous methods no longer public - to make the simple quick reject check logic const - simple quick reject is now conservative This CL also fixes several issues with line and point quickRejection - sub-pixel and hairline lines are much less likely to be incorrectly rejected, especially at small canvas scale. Additionally, alpha modulation for AA points < 1px in size is now correct, dumplicating SW behavior (similar to lines and stroked shapes work). Change-Id: Ibb0710c721b9fb415d05acf54dd3d2b4d602156a
