This test draws a frame of an HDR video to a canvas, getImageData of a certain pixel from the canvas and then compares this pixel with an expected color. Because of 260512@main, the colorspace of the unaccelerated temporary buffer can be different on different platforms. So the drawn pixel might be slightly different from the expected pixel. We need to use a small tolerance when comparing these two pixels.
