-Pandora
-=====================================================================
-
-( http://openpandora.org/ )
-- A pandora specific video driver was written to allow SDL 2.0 with OpenGL ES
-support to work on the pandora under the framebuffer. This driver do not have
-input support for now, so if you use it you will have to add your own control code.
-The video driver name is "pandora" so if you have problem running it from
-the framebuffer, try to set the following variable before starting your application :
-"export SDL_VIDEODRIVER=pandora"
-
-- OpenGL ES support was added to the x11 driver, so it's working like the normal
-x11 driver one with OpenGLX support, with SDL input event's etc..
