* Console Management
|
|
* The console management uses OpenGL, cairo and pango to draw a console to a
|
|
* framebuffer. It is independent of the other subsystems and can also be used
|
|
* in other applications.
|
|
*
|
|
* This console does not emulate any terminal at all. This subsystem just
|
|
* provides functions to draw a console to a framebuffer and modifying the state
|
|
* of it.
