1622226 - Pack more images in the shared texture cache

Status: RESOLVED WORKSFORME

(Core :: Graphics: WebRender, task, P3)

Description

[Nicolas Silva [:nical]]

A lot of batch breaks happen because of draw calls using the same shader but different textures (see https://bugzilla.mozilla.org/show_bug.cgi?id=1594474#c1).

It's worth investigating specifically which types of entry that don't go into the shared texture array break a lot of batches, and whether we can allow more of them to go into the shared texture array somehow.

This seems to be working well right now, I see very few pages with high draw calls. If we get specific bugs / pages with performance issues related to draw call count, let's investigate them.
