Framebuffer support for screen driver

[noxer]

As an alternative to managing the screen withing the driver and offering a terminal the screen driver should support frame buffers so processes can access the screen directly.

So process can be pionted to the memory map of the screen and they can do what they want with it?

Thats the plan. This will be useful for graphical applications. (See VladVP's post in #6)

[noxer]

When an application demands frame buffer access the driver/kernel should check which terminal (screen) to use for this process, then it should check if there is already a frame buffer for this screen and finally it should copy the current content of the screen and font buffers to a new location and point the screen on the new area. then it should return a pointer to the new frame buffer.

Actually the library I'm working on is already intended to support graphical buffers... (yes that's right! not just rendering buffers! ;D )
