HitTestLocation currently makes a 1px box with the location at its top-left for hit-testing. That results in coarser hit-test that necessary. I think we should use a device-pixel sized box.
This becomes more relevant when we allow device-pixel accuracy for pointer events.

This affects fast/frames/iframe-subpixel-hit-test.html which I am adding for bug 294571.

We should also make imported/w3c/web-platform-tests/css/css-transforms/transform-scale-hittest.html pass.

We probably need something like https://chromium.googlesource.com/chromium/src.git/+/c47a6f0b4a592c2383fb553b6169f89ab01d851d
