+
+        [chromium] Defer managed texture creation and destruction until updateCompositorResources
+        https://bugs.webkit.org/show_bug.cgi?id=64772
+
+        Reviewed by Kenneth Russell.
+
+        This adds support for deferring GraphicsContext3D calls for texture creation and destruction for managed
+        textures and defers these calls until updateCompositorResources() for contents textures.  The primary benefit of
+        this change is that it decouples managing the texture budget for the next frame (which has to happen before
+        painting layer contents) from the actual GL calls that create/destroy textures.  That way, in the threaded
+        compositing world we can continue to use textures from the previous frame while software painting contents for
+        the next frame into software buffers or SkPictures.
+
+        Also renames LayerTexture to ManagedTexture to better reflect what it is.  Not all ManagedTextures we create are
+        necessarily associated with layers, but they are all managed by a TextureManager.
+
+        Covered by compositing/ layout tests.

+        iframes with composited layers for content should be able to do fast
