AMD R600/700 2D Performance: Open vs. Closed Drivers

The GtkComboBoxEntry performance was similar but the open-source stack ended with a slight win.

With the GtkDrawingArea - Circles test, the Catalyst 9.10 driver with both the RV670PRO and RV730 graphics cards took the win by a noticeable margin.

The Catalyst 9.10 driver did quite poorly when it came to the GtkDrawingArea - Pixbufs test in comparison to the 2D R600/700 open-source support.
