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.
The top level code handles SDL_WINDOWPOS_CENTERED now, and the Cocoa SetWindowPosition call will clear the moveHack before adjusting the window position.
Fixed creating render texture framebuffer.
Removed the need for palette watch, added surface format caching.
Added an SDL_DONTFREE flag so you can't free the window and 1.2 shadow surfaces.
There's a new event that's always sent when the window changes size, and that event is what the renderers listen for to determine if they need to rebind their context.
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 :-)
I have done some quick changes and at least the code compiles again. It
also works with a number of the test executables with the DFB X11
backend. I hope to find time to get SDLMAME to work with latest SDL1.3
(i.e. rip out multi-keyboard, multi-mice & cursor support) next week to
test it further.
Regards,
André
* Added display parameter to many internal functions so video modes can be set on displays that aren't the public current one.
* The fullscreen mode is associated with fullscreen windows - not displays, so different windows more naturally have a mode associated with them based on their width and height. It's no longer necessary to specify a fullscreen mode, a default one will be picked automatically for fullscreen windows.

Since current DirectFB implementation is incomplete for YUV surfaces (actually causes segmentation faults when trying Lock and use YUV planar textures) I decided to fix it a bit.
Here's a patch that should make DirectFB properly support YUV both packed and planar (3 planes).
(1) Removed SDL_BYTESPERPIXEL at all in favor of DFB_BYTES_PER_PIXEL(SDLToDFBPixelFormat(fmt)) which does return always proper BPP for YUVs too, coz SDL_BYTESPERPIXEL returns incorrect values for FOURCCs
(2) Fixed data->pixels allocation for planar YUVs in CreateTexture, it should allocate 150% more space
(3) Copy other planes for planar YUVs in UpdateTexture
(4) Moved checking if format is supported at all with DirectFB on CreateTexture at the beginning of the code
Waiting for comments,

- 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: SDL1.3 DirectFB patches
The attached contains the following directfb changes:
- Dynamic loading of libdirectfb.so. This may to turned off as well in configure
- Use linux-input by default. May be switched off by environment variable.
- Added some code which will use directfb's x11 backend when DISPLAY is set.
