* Attempt to reland code reverted in r52599, to take another look at the page ↵pkasting@chromium.org2010-07-301-12/+3
| | | | | | | | | | | cycler data. There was a lot of noise in the previous data, and since the current page cycler t and t_ref times are close, I'm hoping to see something more conclusive. TBR=jar BUG=47227 TEST=none Review URL: http://codereview.chromium.org/3026032 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@54236 0039d316-1c4b-4281-b951-d872f2087c98
* Revert 46492 to repair perf regression in XP single-core Moz Page Cyclerjar@chromium.org2010-07-161-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Actually, this only reverts the windows specific portion of 46492. Initial revert and restore (see revisions 52456 and 52441) seemed to show that this was indeed the cause of the regression. There was some problem with the perf bot, so I'm landing again to confirm that this removes the regression. As pointed out by pkasting, this is all browser side computation, but on a single core (as noted by Darin), browser processing becomes critical path (and can impact perf). My suspicioun is that the original code did some caching of its font metrics, and this was not (to the same extent??) being done in the replacement (centralized) code. If this does not provide the perf fix I'm expecting, I'll revert it.

* Revert 52441 - Revert Win specific elements of 46492 to look for perf impactjar@chromium.org2010-07-151-12/+3
| | | | | | | | | | | | | | | | | | | | There was a regression in the moz page cycler around when landed. This was ONLY a single core regression, which suggests it was time spent in the browser becoming critical path. This change involved font layout in the browser, and so it MIGHT be related. I'll land this, let the per bots start their run, and then revert.

* Canvas refactoring part 3.ben@chromium.org2010-06-251-2/+3
| | | | | | | | | | | | | | - Replace Canvas instance users with CanvasSkia users. - Rename Canvas2 to Canvas. - Delete Canvas subclass of CanvasSkia. This has created some ugliness around the fact that people that used SkCanvas methods on Canvas now have to go through AsCanvasSkia first. This is temporary ugliness that will be eradicated as I incrementally build out the new Canvas API.

* Make Font::GetStringWidth() a shortcut for gfx::Canvas::SizeStringInt() on ↵pkasting@chromium.org2010-05-051-13/+4
| | | | | | | | | | | | Windows. These two functions already did the same thing on Mac and Linux. If they ever returned different results on Windows, it would lead to subtle bugs, since measurement and drawing would slightly disagree. Clean up a few other things so that all three implementations of GetStringWidth() are identical.
