Detailed Description

Determines the drawing coordinates.

****************************************************************************

The CoordSys structure holds a "coordinate system" defined by a rectangle (left, right, bottom, and top) which determines how drawing coordinates are mapped to the screen.

Note:

The default coordinate system is (0, 1024, 0, 768), which is the same as the game's default 1024x768 resolution.
