[WinCairo] GraphicsContextGL should have one more output texture for double buffering WebGL

WinCairo's GraphicsContextGL has only a single output texture now.
The WebGL output can get broken if the page is interactive.
For example, Google Maps is using WebGL for the map.
If a user is drugging the map, the map becomes blank.
