// Description:

// e32test\buffer\t_graph.cpp

// Overview:

// Test the TPoint, TSize, TRect class.

// API Information:

// TPoint, TSize, TRect.

// Details:

// - Initialize some two-dimensional points in Cartesian co-ordinates with various 

// positive, negative values. Add and subtract different initialized points and 

// check that results are as expected.

// - Create some two-dimensional sizes, set with various positive, negative values. 

// Add and subtract different initialized sizes and check that results are as expected.

// - Initialize some rectangles in different positions, set various widths, heights and 

// sizes and verify that values are assigned as specified. 

// - Move the rectangle by adding two-dimensional point offset, some x, y offset and check 

// that it is as expected.

// - Resize, shrink, grow, rectangles by adding, subtracting some horizontal, vertical 

// offset and verify that it is as expected.

// - Get the minimal rectangles which bounds one rectangle and the specified rectangles, 

// assign it to the rectangles and check that it is as expected.

// - Assign some rectangles with different positions and test whether the rectangle is 

// empty, overlaps as expected.

// - Get the area of intersection between one rectangle and the specified rectangle, 

// assign it to the rectangle and verify that the assigned rectangle is not empty.

// - Create some rectangles, check that the rectangle's width and height have positive

// values, the rectangle is normalized, whether a point is located within the rectangle 

// and is empty.

// - Create some rectangles, get the points at the centre of the rectangles and check that 

// it is as expected.

// - Create  some three-dimensional points in Cartesian co-ordinates with various 

// positive, negative values. Add and subtract different initialized points and 

// check that results are as expected.
