Andrew Osmond e69fa7da55 Bug 1818047 - Add prefs to control WebRender scissored cache clears. r=gfx-reviewers,jrmuizel
This patch adds two new prefs, gfx.webrender.scissored-cache-clears
.enabled and .force-enabled to control its status beyond the blocklist.
The former is true by default and allows one to turn the feature off by
flipping it to false. The latter allows one to force the feature on even
if the blocklist disables it. It also adds the status to the decision
log in about:support.
