1584017 - (wr-android-apz) [meta] APZ issues needed for WebRrender on Android

Status: NEW

(Core :: Graphics: WebRender, enhancement, P5)

Description

[Botond Ballo [:botond]]

This bug tracks APZ related work that needs to be done for WebRender on Android.

This is mostly WebRender implementations of APZ features that are mobile-specific and which we therefore haven't cared about so far (prior to bringing WR to Android).

Examples are:

• Implementing the setVerticalClipping API (used by GeckoView to implement Fenix's dynamic toolbar) for WebRender (bug 1583380)
• Getting WebRender's position:sticky implementation to behave well in the presence of pinch-zooming (bug 1569339)
• Getting fixed-position hit testing working correctly with WebRender (basically, the WebRender equivalent of bug 1522714)

There are probably other things I'm not thinking of right now.
