NAME

AG_DriverSDL2FB — agar SDL2 frame-buffer driver

DESCRIPTION

The Agar sdl2fb driver provides an interface to the Simple DirectMedia Layer (SDL) library version 2 (SDL2), and renders Agar GUI elements directly to the frame-buffer.

Using AG_InitVideoSDL(3) as opposed to AG_InitGraphics(3), it is possible to attach Agar to an existing SDL2 display surface.
