>>TITLE XRectInRegion CH10
>>ASSERTION A XRectInRegion-1
When the rectangle specified by the x, y, width, and
height arguments is entirely in the region r, then a call
to XRectInRegion returns RectangleIn.
>>STRATEGY
Create a region using XCreateRegion.
Set the region to a rectangle using XUnionRectWithRegion.
Verify that with a contained rectangle XRectInRegion returns RectangleIn.
>>ASSERTION A XRectInRegion-2
When the rectangle specified by the x, y, width, and
height arguments is entirely out of the region r, then a
call to XRectInRegion returns RectangleOut.
>>STRATEGY
Create a region using XCreateRegion.
Set the region to a rectangle using XUnionRectWithRegion.
Verify that with a non-intersecting rectangle XRectInRegion returns RectangleOut.
>>ASSERTION A XRectInRegion-3
When the rectangle specified by the x, y, width, and
height arguments is partly in the region r, then a call to
XRectInRegion returns RectanglePart.
>>STRATEGY
Create a region using XCreateRegion.
Set the region to a rectangle using XUnionRectWithRegion.
Verify that with an intersecting rectangle XRectInRegion returns RectanglePart.
