+// Description:
+// e32test\buffer\t_regn.cpp
+// Overview:
+// Test fixed and variable clipping regions.
+// API Information:
+// TRegionFix, RRegion .
+// Details:
+// - Construct some expandable clipping regions, add some rectangles, check the region
+// matches the rectangles, clear the region, add some rectangles to the region and
+// check the region matches the rectangles.
+// - Copy one region to another, using the Copy method and the copy constructor,
+// and check the region matches the rectangles.
+// - Create a some fixed clipping regions, add some rectangles, check the region
+// matches the rectangles, clear the region, add some rectangles, and check the
+// region matches the rectangles.
+// - Copy one fixed region to another, using the Copy method and the copy constructor,
+// and check the region matches the rectangles.
+// - Test TRegionFix creation and error handling using Clear, Count, AddRect, CheckError
+// and Tidy methods
+// - Test adding rectangles, via AddRect, to an RRegion object. Verify the results
+// via the Count, BoundingRect and IsEmpty methods.
+// - Test subtracting rectangles, via SubRect, from an RRegion object. Verify the
+// results via the Count, BoundingRect and SubRegion methods.
+// - Test subtracting regions, via AddRect and SubRegion, from an RRegion object.
+// Verify the results via the Count, BoundingRect, Clear, Copy, and SubRect methods.
+// - Test the RRegion Tidy method. Verify the results via the Count, AddRect,
+// BoundingRect and Clear methods.
+// - Test the RRegion CheckSpare method. Verify the results via the AddRect, Tidy,
+// Clear and SubRect methods.
+// - Test the RRegion Offset method. Verify the results via the AddRect, Move,
+// Clear, IsEmpty and RectangleList methods.
+// - Test the RRegion Intersection and Intersect methods. Verify the results via
+// the AddRect, Count, IsEmpty and RectangleList methods.
+// - Test the RRegion Union method. Verify the results via the AddRect, Count,
+// Copy, Offset and BoundingRect methods.
+// - Test the RRegion ClipRect method. Verify the results via the AddRect, Count,
+// and BoundingRect methods.
+// - Test the RRegion and TRgionFix Contains methods. Verify the results via the
+// AddRect method.
+// - Test the RRegion ForceError and CheckError methods. Verify the results via the
+// AddRect, Copy, Count, SubRect, Clear and BoundingRect methods.
+// - Test the RRegion and RRegionBuf sort method.
+// - Construct some regions with pre-allocated buffer (RRegionBuf), add some rectangles,
+// get a pointer to the array of rectangles defining this region and check the
+// rectangles are as expected.
