Revert of Simplify IOSurface CoreAnimation code: Part 2 (patchset #13 id:240001 of https://codereview.chromium.org/490393002/) Reason for revert: crbug.com/410360 (Browser crashing on IOSurfaceLayer release in tab_switching.typical_25) Original issue's description: > Simplify IOSurface CoreAnimation code: Part 2 > > It isn't necessary to mess around with sharing CGLContextObjs anymore, > they were necessary only to share data between the frame subscriber > and the RenderWidgetHostViewMac. Just give each IOSurfaceLayer its > own CGLContextObj, and draw using immediate mode (using shaders > resulted in an increase in startup time). > > BUG=314190 > TBR=pfeldman@chromium.org > R=kbr@chromium.org > > Committed: https://chromium.googlesource.com/chromium/src/+/a83898264f64ad83bb98139e5e0dcb2c77db1997 TBR=kbr@chromium.org,ccameron@chromium.org NOTREECHECKS=true NOTRY=true BUG=314190 Review URL: https://codereview.chromium.org/528403002 Cr-Commit-Position: refs/heads/master@{#293174}
