/**
|
||||
* Used for drawing graphics. It contains all vital functions for drawing.
|
||||
* We include implemented Graphics classes for some common platforms like
|
||||
* the Allegro library, the OpenGL library and the SDL library. To make
|
||||
* Guichan usable under another platform, a Graphics class must be
|
||||
* implemented.
|
||||
*
|
||||
* In Graphics you can set clip areas to limit drawing to certain
|
||||
* areas of the screen. Clip areas are put on a stack, which means that you
|
||||
* can push smaller and smaller clip areas onto the stack. All coordinates
|
||||
* will be relative to the topmost clip area. In most cases you won't have
|
||||
* to worry about the clip areas, unless you want to implement some really
|
||||
* complex widget. Pushing and poping of clip areas are handled
|
||||
* automatically by container widgets when their child widgets are drawn.
|
||||
*
|
||||
* IMPORTANT: Remember to pop each clip area that you pushed on the stack
|
||||
* after you are done with it.
|
||||
*
|
||||
* If you feel that Graphics is to restrictive for your needs, there is
|
||||
* no one stopping you from using your own code for drawing in Widgets.
|
||||
* You could for instance use pure SDL in the drawing of Widgets bypassing
|
||||
* Graphics. This might however hurt portability of your application.
|
||||
*
|
||||
* If you implement a Graphics class not present in Guichan we would be very
|
||||
* happy to add it to Guichan.
