This required a small public API change: SDL_GL_SetSwapInterval() now accepts
negative values, and SDL_GL_GetSwapInterval() doesn't report errors anymore
(if it can't work, it'll return zero as a reasonable default).
If you need to test for errors, such as a lack of swap_control_tear support,
check the results of SDL_GL_SetSwapInterval() when you set your desired
value.
attached is a working directfb driver diff which works with the current
changes. There are a number of changes around it as well, e.g.
configure.in.
The directfb renderdriver right now still depends on a some "includes"
from src/video/directfb. That's why it is not yet moved to the new
render folder.
Hi Sam,
20100815_1.diff contains updates for the directfb driver:
- more documentation, mainly on software OpenGL in README.directfb
- Revised error handling leading to leaner code
- Improved/fixed OpenGL handling of multiple contexts.
- Made the built-in simple window manager handle OpenGL windows.
- Rewrote pixelformat mapping - this was quite ugly before.
Well, all software GL, but working :-)
- use SDL_getenv, not getenv ...
- no more support for 0.9.25 - not even mentioned any longer on directfb.org
- fix fullscreen issues
- add a simple window manager unless the directfb team comes up with a working wm.
The driver has support for a very, very basic window manager you may
want to use when runnning with "wm=default". Use
export SDL_DIRECTFB_WM=1
to enable basic window borders including icon support. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf

Subject: Re: Updated DirectFB driver for SDL1.3
attached is a patch which brings the directfb driver in line with
current svn. In addition:
* driver now is in line with the structure of the X11 driver.
This adds a couple of files.
* driver now supports relative mouse movements
