fast/canvas/canvas-ImageData-behaviour.html fails on chromium after r64156. Looks like data type and rounding issue.

Here are the example of actual output on chromium win:

PASS imageData.width is 2
...
FAIL imageData.data[0] = -1, imageData.data[0] should be 255. Was 0.
PASS imageData.data[0] = "0", imageData.data[0] is 0
...
FAIL imageData.data[0] = Infinity, imageData.data[0] should be 0. Was 255.
PASS imageData.data[0] = -Infinity, imageData.data[0] is 0
FAIL imageData.data[0] = -5, imageData.data[0] should be 251. Was 0.
PASS imageData.data[0] = -0.5, imageData.data[0] is 0
