Tests how long it takes format and draw a CRichText object.

Create a complex font control. Format and draw the text control each time
it receives a left pointer down event. The test step and the drawing of the
control is synchronized with a Semaphore. 

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