Message:

Add a new graphics test for CanvasRenderingContext2D functions: getImageData and putImageData
​https://bugs.webkit.org/show_bug.cgi?id=151716

Patch by Said Abou-Hallawa <​sabouhallawa@apple.com> on 2016-02-05
Reviewed by Darin Adler.

The purpose of this test is to measure the performance of getImageData
and putImageData functions. This test draws a background on the canvas
and then gets some random tiles from this background and draw them in
destinations different from their original sources.

• Animometer/resources/debug-runner/tests.js: Adding the new test to the canvas simple tests suite.

• Animometer/resources/extensions.js:

(Array.prototype.shuffle): Shuffles the elements of an array.

(Point.zero): Returns a new Point object whose x and y are equal zero.
(Point.prototype.str): Used for debugging the Point object.

• Animometer/tests/simple/resources/tiled-canvas-image.js: Added.

(CanvasImageTile):
(CanvasImageTile.prototype.getImageData):
(CanvasImageTile.prototype.putImageData):
(Stage.call.initialize):
(Stage.call._createTiles):
(Stage.call._nextTilePosition):
(Stage.call.tune):
(Stage.call._drawBackground):
(Stage.call.animate):
(Stage.call.complexity):
(Stage.call):

• Animometer/tests/simple/tiled-canvas-image.html: Added.
