Subject: [PATCH] perf: Add metrics for different window configurations

Add metrics:
 overviewFps5Windows
 overviewFps10Windows
 overviewFps5Maximzed
 overviewFps10Maximized
 overviewFps5Alpha
 overviewFps10Alpha

To have more numbers to show how performance varies with different
numbers of windows and different types of windows (maximized,
with an alpha channel.)
