\class DisplayDriver DisplayDriver.h
|
|
\brief Mostly abstract class which handles all graphics output for the server.
|
|
|
|
The DisplayDriver is called in order to handle all messiness associated with
|
|
a particular rendering context, such as the screen, and the methods to
|
|
handle organizing information related to it along with writing to the context
|
|
itself.
|
|
|
|
While all virtual functions are technically optional, the default versions
|
|
do very little, so implementing them all more or less required.
