comparison include/mb_redraw_man.h @ 462:af4b506ad56f

Add backend layer to seperate the backend with the MBAF. Currently, X is the only backend. If we have more than one backend, we need to modify the Makefile to sleect the backend or implement a backend selection mechanism in the runtime.

235 * A backend is used to receive events from the system. The MB does not define the backend by itself.
236 * Instead, it define an interface which allow the lower layer to implement the event system. Each
237 * backend need to provides the following events.
238 *
239 * - keyboard event
240 * - timer event
241 * - image loader(?)
