>>TITLE XSetGraphicsExposures CH05
>>ASSERTION A XSetGraphicsExposures-1
A call to XSetGraphicsExposures sets the graphics_exposures
component of the specified GC to the value of the
graphics_exposures argument.
>>STRATEGY
Create window.
Create child window partially obscuring parent.
Create GC with graphics_exposures = True.
Flush event queue with XSync.
Copy from parent window using XCopyArea.
Verify that a GraphicsExpose event was generated, 
Set graphics_exposures = False with XSetGraphicsExposures.
Flush event queue with XSync.
Copy from parent window using XCopyArea.
Verify that no event was generated.
>>ASSERTION B XSetGraphicsExposures-2
When the server fails to allocate a required resource, then
a BadAlloc error occurs.
>>STRATEGY
Report UNTESTED
>>ASSERTION A XSetGraphicsExposures-3
When the GC argument does not name a defined GC, then a
BadGC error occurs.
>>STRATEGY
Create a GC.
Set GC id to -1 using XTestSetGContextOfGC.
Call test function using bad GC as the GC argument.
Verify that a BadGC error occurs.
>>ASSERTION A XSetGraphicsExposures-4
When the value of graphics_exposures is other than True or
False, then a BadValue error occurs.
>>STRATEGY
Obtain a sequence of values which are not in the list specified by VALUE_LIST.
For each value:
  Call test function with this value in the VALUE_ARG argument.
  Verify that a BadValue error occurs.
