Bug 69798 – Touch events should take page scale into account

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[John Knottenbelt]

Event coordinates are in CSS pixels, so they should take the page scaling into account when converting from PlatformTouchEvent coordinates (which is in screen pixels).

If any of these errors are false positives, please file a bug against check-webkit-style.

Thanks for reviewing, Hajime. Expectations now included.

I also changed the test to be more similar to the test it is derived from, bringing the coordinates of the gesture closer together so that they are recognised as a click (rather than say, a swipe).

The style bot had a wobbly on this day - there weren't any style problems detected by webkit-patch upload.

I'd really appreciate it if someone could review. 

Thanks.

I spoke to John, I am able to repo the bug locally on http://www-cs-students.stanford.edu/~eparker/files/maps/visualize_touch_events.html.

This looks like a good fix, IMHO.

Simon, could you please take a look at this? Thanks.
