[GTK] webgl/1.0.x/conformance/extensions/webgl-multi-draw.html fails after 2022-08-02 WebGL conformance test update

Updated in bug 243448


Likely not multi draw related, rather compositing / swap issue revealed by the additional tests added in the new version of the test.

There were two recent changes to this test:

1) https://github.com/KhronosGroup/WebGL/pull/3443

The associated bug fixes to this test were:

Implicit extension enabling should use WebGL frontend
https://bugs.webkit.org/show_bug.cgi?id=241918

Chromium-side bug was:
WebGL extensions must enable dependent ones
https://crbug.com/1343108

2) https://github.com/KhronosGroup/WebGL/pull/3437

The associated bug fix was:

Align WebGL draw call functions 
https://bugs.webkit.org/show_bug.cgi?id=241347

If the GTK port's using ANGLE as its WebGL implementation then these should have been picked up automatically.

After replacing the WebGL backend with ANGLE this test is fixed. The gardening commit is:
