\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.
