  Message : Implement ANGLE_program_cache_control extensions. This will give the browsers the ability to control the cache size, query and populate the contents, and trim cache contents on memory pressure. BUG=angleproject:1897 Change-Id: I6edaa7d307b890223db98792d5b074e4a7fdfaa4 Reviewed-on: https://chromium-review.googlesource.com/563606 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org>
