8234471: Canvas in webview displayed with wrong scale on Windows

[arun-joseph]

This bug can be reproduced when the screen resolution is at 125%, 150% and 175% for Windows, which correpsonds to pixelScale values of 1.25, 1.5 and 1.75, respectively.

Issue: The rectangle inside canvas is rendered on pixelScale while the borders are rendered on Math.ceil(pixelScale)

Fix: Use Math.ceil(pixelScale) for calculating pixelScaleTransform

The number of required reviews for this PR is now set to 2 (with at least 1 of role reviewers).

[kevinrushforth]

This looks like the correct fix, and I can confirm that it does fix the problem. I'll run a set of regression tests on Windows 10 with 125% scaling (which is my normal environment) and then finish my review.

[kevinrushforth]

The fix looks good to me. I left one comment on the test.
