This patch shouldn't have any functional effect. It's motivated by some changes needed to implement clip masks in pixel local storage, but these are also general improvements that stand alone. Specifically: - Remove clip_task_index from the global PrimitiveHeader struct. In most cases, the clip task is supplied in the BrushInstance structure, so it makes no sense to have this as a common field, where it is generally unused. Instead, there is now an extra 'user data' field available in the PrimitiveHeader. Non-brush shaders (text_run and split_composite) use that extra field to store the clip task address, while the brush shaders gain an extra (currently unused) user data field. - In turn, this means there is no need to unconditionally try and retrieve the first clip task address for a primitive during batching. This was previously used to initialize the PrimitiveHeader structure. Differential Revision: https://phabricator.services.mozilla.com/D24312 --HG-- extra : moz-landing-system : lando |
