From 12076fa6270fda6ea535da61cafe7116ec2e6f00 Mon Sep 17 00:00:00 2001 From: "avallee@chromium.org" Date: Thu, 24 Oct 2013 22:51:36 +0000 Subject: Add Color animation curves. Implement animation curves for colors. This is the first step towards accelerating background-color animations. + Add ColorValueBetween to gfx::Tween. + Add test/color_utils which gives EXPECT_COLOR_EQ to check SkColors and print in a sane format. ~ Fixed discrepancy between two methods of interpolating ints. ~ Factored out GetProgress into template function to simplify code in the implementations of GetValue(double), there was a lot of duplication there. TESTED: Added tests for the new KeyframedColorAnimations and AnimatedColor classes. Added tests to tweening.
