        [chromium] compositor lost context recovery fix
        https://bugs.webkit.org/show_bug.cgi?id=50614

        To test, load a page that triggers the compositor, kill the GPU
        process and hover over a link to redraw and thus restart the GPU
        process.  Without this patch it will assert in
        ContentLayerChromium::updateTextureRect; with this patch it will not.

        * platform/graphics/chromium/LayerChromium.cpp:
        (WebCore::LayerChromium::setNeedsDisplay):
