Ryan C. Gordon 98c03f391d Changed drag area API to a hit-testing API.
There were several good arguments for this: it's how Windows works with
 WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more
 control over the regions (how do you use rects to cleanly surround a circular
 button?), the callback can be more optimized than a iterating a list of
 rects, and you don't have to send an updated list of rects whenever the
 window resizes or layout changes.

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings 
available for several other languages, including C# and Python.

This library is distributed under the zlib license, which can be found
in the file "COPYING.txt".

The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
