+Subject: [PATCH] ANGLE: Do not reset the share handle when resetting the swap
+ chain.
+
+This change only affects the ANGLE_surface_d3d_texture_2d_share_handle
+extension. The patch is necessary to have WebGL running in Qt/WebKit2.
+
+If the share handle is reset, we are loosing the reference to the
+EGLSurface and cannot actually reuse it in a different context anymore.
