From 8927bcfd339510deedb89ff274ea9cd1d00a2668 Mon Sep 17 00:00:00 2001 From: aliguori Date: Thu, 15 Jan 2009 22:07:16 +0000 Subject: [PATCH] remove bgr (Stefano Stabellini) Do not handle bgr host displays in the backends. Right now a bgr flag exists so that sdl can set it, if the SDL_Surface is bgr. Afterwards the graphic device (e.g. vga.c) does the needed conversion. With this patch series is sdl that is responsible for rendering the format provided by the graphic device that must provide a DisplaySurface (ds->surface) in 16 or 32 bpp, rgb. Afterwards sdl creates a SDL_Surface from the given DisplaySurface and blits it into the main SDL_Surface using SDL_BlitSurface. Everything is handled by sdl transparently, because SDL_BlitSurface is perfectly capable of handling bgr displays by itself.
