Description Felipe Heidrich

Currently StyledText draws the text selection trim by using GC#fillRectangle (int, int, int, int). 

This limits how the selection is drawn in many ways:
 - it is always drawn before or after the text
 - it is always a rectangle
 - it is always a solid color

In some platforms this can cause the selection in StyledText to differ from the native behaviour:
In Mac, the text selection can have trapezoid form
In WPF, the text selection is drawn using alpha transparency

We suggested to fix this by moving all the text selection drawing down to TextLayout.

We need to add API to TextLayout to allow us to draw the text selection correctly on Vista, then call that API from StyledText.

Steve, I assume this has your PMC +1 for API added after the API freeze.

Yes, it was approved on the pmc list by someone other than me.
