<pre>Add basic canvas tests
https://bugs.webkit.org/show_bug.cgi?id=150066
rdar://problem/23081143
Reviewed by Dean Jackson.
This adds a new test suite that will cover all of the path-based canvas calls.
The patch will be divided up to cover tests with similar techniques.
The simplest version uses a SimpleCanvasStage.
* Animometer/runner/resources/tests.js: Add tests for quadratic, bezier, arcTo,
arc, and rect segments. Also include arcTo, arc, and rect fills.
* Animometer/tests/resources/stage.js:
(Stage.prototype.randomBool): Added for counterclockwise property for arc segments.
(Stage.prototype.randomInt): Fix how values are rounded, used by randomBool. It should
round instead of flooring everything.
* Animometer/tests/simple/resources/simple-canvas.js: Added. Defines common classes
used by all simple canvas tests. The page reads best bottom to top.
(SimpleCanvasStage): Basic stage. Pass a canvasObject which will be used to create new
objects as needed in tune().
(SimpleCanvasStage.prototype.tune): Modeled on other tests. Adds and removed objects
as specified by the provided |count|.
(SimpleCanvasStage.prototype.animate): Iterate over all the objects and ask them to draw.
There is no "animating" of the objects; they will just paint statically on the canvas.
(SimpleCanvasAnimator): Basic animator clears the canvas prior to painting.
(SimpleCanvasBenchmark): Hard-code the feedback loop parameters instead of including
them in the query parameters to the test URLs.
(SimpleCanvasBenchmark.prototype.createAnimator):
* Animometer/tests/simple/simple-canvas-paths.html: Added.
* Animometer/tests/simple/resources/simple-canvas-paths.js: Added. There is no "animating"
of these objects--they just paint statically on the canvas.
(CanvasQuadraticSegment): Paint a quadratic segment stroke.
(CanvasBezierSegment): Paint a bezier segment stroke.
(CanvasArcToSegment): Paint an arcTo stroke.
(CanvasArcSegment): Paint an arc stroke.
(CanvasRect): Paint a rect.
(CanvasRectFill): Paint a filled rect.
(CanvasPathBenchmark):
(CanvasPathBenchmark.prototype.createStage): Look for the pathType and create the
stage using the right paint object.
