* Adds a command line flag to suppress flashing blinking for those who really, ↵slightlyoff@chromium.org2010-03-011-2/+17
| | | | | | | | | | | REALLY want it to stop. BUG=None TEST=load tons of tabs after starting with --disable-backing-store-limit and observe no blinking and HUGE memory usage.

* Add the ability for the GPU process to be used to paint the backing store of abrettw@chromium.org2010-01-131-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tab. This is the first pass and is currently a bit buggy and incomplete. This patch refactors the backing store to make it a virtual interface which is then implemented by the platform-specific backing stores. This cleans up the multi-platform aspects of the old code, and also makes it possible to create different backing stores (such as ones in another process). This renames the BackingStore::PaintRect function to PaintToBackingStore which clears up what it does. I would often get confused and think that it paints the backing store to the screen. This makes a common way to capture backing store information and adds it to the backing store API. This removed a bunch of ugly ifdefs. This adds the ability for a backing store to specify that the TransportDIB should not be freed by RenderWidgetHost when painting is complete. This is necessary since the out-of-process version needs to use it after the RenderWidget paint function has returned. This pushes up the vector of copy_rect from RenderWidgetHost to the actual BackingStores. This prevents us from sending duplicate data over IPC. It also makes the common non-IPC case more efficient, since we end up setting up various surfaces only once when there are multiple update rects.

* Preserve optimized scrolling in the presence of multiple animating rects.darin@chromium.org2009-12-041-2/+26
| | | | | | | | | | | | | | Change PlatformCanvas so that it only fills with "sea foam green" when bitmap data is not externally supplied. Modifying the interface to make this an option bloated the CL too much. I may do this as a follow-up. Adds a new --show-paint-rects command line flag that will render a border around paint rects to help debug and study WebKit painting issues.

* Adds kind-of-live thumbnail generation for a potential tab switcher.brettw@chromium.org2009-06-161-9/+42
| | | | | | | | | | | | | | | | | | | | This listens to tab events and tries to keep thumbnails ready to go. See thumbnail_generator.cc for a more detailed design. This adds a painting observer to the RenderWidgetHost to enable this new behavior, as well as a notification to allow the thumbnail generator to hook its observer in. There is also a new notification that a backing store has been disabled, which required making the backing stores know about their owning widget hosts. This component is currently disabled. We just need to uncomment the member in Profile and it will start to work.
