@SYMTestCaseDesc

Choose a suitable extent to test that specified border colours are correct.

@SYMTestActions

For a number of different situations, do the following:

1. Create a window of known size

2. Create a fixed size surface, filled in with a predefined bitmap

3. Draw the surface onto the window for a set extent and border colour

4. Compare window content and border against a reference bitmap containing expected values. 

@SYMTestExpectedResults

The window content matches the independently created reference bitmap in each situation
