Measures the performance of DrawBitmap() for the current screen mode, for various bitmap pixel formats.
The bitmap is drawn without scaling.
@SYMTestActions
Create a copy of the bitmap, and scale to the required size, prior to running the test.
For each required source pixel format, use DrawBitmap() to tile a bitmap across the target, avoiding any
clipping or overlap.

The performance to be logged as a pixel rate, per bitmap.
