1873541 - Avoid using GfxDriverInfo::allFeatures, convert uses to new optionalFeatures

Status: RESOLVED FIXED

(Core :: Graphics, defect, P3)

Description

[Andrew Osmond [:aosmond] (he/him)]

optionalFeatures should include all features that return true in GfxInfoBase::OnlyAllowFeatureOnKnownConfig:
https://searchfox.org/mozilla-central/rev/43c40b22c776d098afb89d5237da3464a7545532/widget/GfxInfoBase.cpp#1523

Any hard coded blocklist entry using allFeatures should switch to optionalFeatures. That will allow us to try using the GPU process, as well as stop blocking WebGL OOP, ANGLE and backdrop filter.

These entries should affect relatively few users, but represent some of the last hold outs dropping the GPU process.

Attachment: Bug 1873541 - Convert gfx blocklist entries for all features to subset excluding likely safe set.

This patch makes it so that we avoid blocking all features with the
blocklist, and instead continue to allow the safe subset proscribed by
GfxInfoBase::OnlyAllowFeatureOnKnownConfig. Any feature allowed in an
unknown configuration should be allowed in a blanket blocklist entry,
unless we know for a fact that we need to also block them.
