Description

Warm up DWM prior to lowering token. DWM was introduced with Windows Vista. DwmFlush seems to be sufficient to warm it up before lowering the token. DWM is required to present to a window with Vista and later and this allows us to do so with the GPU process sandbox enabled. Enabling the sandbox for this case is not in this patch. Other things are required, such as making the sandbox broker allow certain event objects to be opened from the GPU process. Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=221859
