@SYMTestCaseID

@SYMTestCaseDesc
Tests how long it takes to pan a bitmap in reaction to pointer events.

@SYMTestActions
Create the bitmap and generate the pointer events. Depending on the location of the
pointer the bitmap is drawn to the screen. 

@SYMTestExpectedResults
Test should pass and display the average framerate for the whole test.
