changed macro MAX_G_FORCE to SDL_IPHONE_MAX_GFORCE and moved it to the SDL_config_iphoneos.h file. This should allow users to convert between the Sint16 returned by polling the joystick and units of g-force, which better describe what is going on with the iPhone (and are what the iPhone OS actually gives you). This conversion wouldn't be necessary except that we'd need floating point to store everything as g-force.
5 - Hardware YUV overlays
6 - OpenGL - software only
7 - 2D/3D accelerations (depends on directfb driver)
11 DirectFB 1.0.0 - required
12 Kernel-Framebuffer support: required: vesafb, radeonfb ....
13 Mesa 7.0.x - optional for OpenGL
15 As of this writing 20070810 you need to pull Mesa from git and do the following:
17 ------------------------
22 echo Installing - pleaser enter sudo pw.
24 sudo make install INSTALL_DIR=/usr/local/dfb_GL
25 cd src/mesa/drivers/directfb
27 sudo make install INSTALL_DIR=/usr/local/dfb_GL
28 ------------------------
30 To run the SDL - testprograms:
32 export SDL_VIDEODRIVER=directfb
33 export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
34 export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
38 To use hardware accelerated YUV-overlays for YUV-textures, use:
40 export SDL_DIRECTFB_YUV_DIRECT=1
42 This is disabled by default. It will only support one concurrent
43 overlay and may behave strange if not used with SDL_CreateYUvOverlay
