Adds support for the OnAcceleratedPaint callback. Verified to work
on macOS and Windows. Linux support is present but not implemented
for cefclient, so it is not verified to work.
To test:
Run `cefclient --off-screen-rendering-enabled --shared-texture-enabled`
- Windows: 10.0.19041 SDK is now required.
- macOS: 10.15.1 SDK (at least Xcode 11.2) is now required.
- Remove CefMediaSource::IsValid and CefMediaSink::IsValid which would
always return true.
This includes the following changes:
- Update usage of surface IDs to match the Aura implementation from the
RWHVAura/Window classes.
- Batch CefBrowserHost::WasResized calls to avoid excessive/unnecessary calls
to SynchronizeVisualProperties.
- Cache the results of CefRenderHandler::GetViewRect after resize and make
RWHVOSR::GetViewBounds the source of truth for all size calculations.
- Fix bounds calculations in CefVideoConsumerOSR with GPU enabled.
Known issues:
- The size passed to OnPaint may be off by 1 pixel in cases where the device
scale factor is not 1 and does not divide evenly into the pixel size. This is
due to the inexact conversion from integer pixel size to integer logical size
for GetViewRect.
