Subject: Re: [SDL] SDL 1.2.8 Prerelease
I'm sending small fix for BeOS, which prevents filling up SDL's message
queue too fast.
Without it, SDL receives "key down" messages from BeOS code, for each key
repeat (BeOS handles key repeats itself, and application can check if
received "key down" message from BeOS is first time key down, or if it's
repeat, and which repeat it is). Since there is no way for "sdl driver" to
turn off "default" SDL's key-repeat mechanism, they were working both at
the same time (and queue could be filled up very fast).
So this patch removes handling "key down" message from BeOS if it's
key_repeat "type".

Subject: [SDL] SDL_SaveBMP width bugfix
this fixes the pitch versus width difference that can happen
(especially for 8bit and 24bit (with the exact RGBAmasks) surfaces)
when you use SDL_SaveBMP. The problem was the pitch was used
instead of the width, which in some cases is much wider than the
screen area you really want to save...making for ugly crud on the
saved image borders.
This code has been tested with & without pitch overhangs...and
with the right masks for 24 bit surfaces.
I tested 8,15,16,24,32-0RGB,32-RGBA(with no SDL_SRCALPHA flag).

Subject: Re: [SDL] Problem compiling SDL 1.2.7
- there is a bug that was introduced in the kernel headers for 2.6.9
which is fixed in 2.6.10. This bug *will* byte when compiling the cdrom
subsystem. A patch that works around this bug is attached. Note that
users affected are not those running 2.6.9, but those using the 2.6.9
kernel headers for their system (i.e. whose libc is built against 2.6.9
headers).

Subject: [SDL] Patch: fixing uninitilized palette
while running Valgrind over my application I found the following
problem in SDL:
The function MapNto1 allocates SDL_Color colors[256] but does not
initialize it.
SDL_DitherColors is then called which initialized the r, g and b
component, but not the 'unused' component of each color.
When Map1to1 is called from MapNto1, it runs a memcmp on the colors,
which also evaluates the unused component and therefor returns
differences much more often than necessary.
So the 'unused' component of SDL_Color should be initialized. This
patch does this by calling memset for the whole array in MapNto1 .

Subject: OS X Mouse inversion problem fix (again)
Here's yet another patch for the OS X mouse inversion
problem. This should fix the problem once and for all.
I know I've said this before, but *This time for
sure!* :)
If you recall, my last patch broke the non-OpenGL
windowed code and caused the inversion to occur there
instead. Max submitted a patch that partially reverted
the changes back which included the os version hack
which is currently the most recent CVS.
Aaron Sullivan identified and reported to the mailing
list the other day, that the last partial regression
of the code broke OS X 10.2. Looking over the results,
I'm thinking that I was slightly more successful than
I thought at unifying the code. I think I was trying
to unify the code base for OpenGL and non-OpenGL
windowed modes for all versions of the OS. It looks
like I failed at at unifying the OpenGL and non-OpenGL
code, but I did succeed at unifying the OS versions.
Thus, we no longer need the hack for the OS version
checks. The partial regression still included an OS
check which is what broke things for < 10.3.
Attached is the patch for SDL_QuartzWM.m. It basically
is a half-line change that removes one of the two
checks that decides if the mouse coordinates need to
be inverted, i.e:
if (system_version >= 0x1030 &&
(SDL_VideoSurface->flags & SDL_OPENGL) )
becomes this:
if(SDL_VideoSurface->flags & SDL_OPENGL)
With Aaron's outstanding help, we have collectively
tested:
windowed OpenGL
windowed non-OpenGL
fullscreen OpenGL
fullscreen non-OpenGL
under OS X 10.2 (Jaguar), 10.3 (Panther), and 10.4
(Tiger).
We don't have access to 10.0 or 10.1, but since the
original problem didn't materialize until 10.3, I'm
hopeful that testing 10.2 is sufficient. And now that
the code is uniform, I'm also hoping we'll be safe
moving forward to deal with future revisions of the OS
with this issue.

Subject: [SDL] [PATCH] DirectX and SDL_WINDOWID Hack
Hello, all. The IDirectInputDevice2_SetCooperativeLevel call in
SDL_dx5events.c expects to be passed a root-level HWND. More often than not,
a child window is used with the SDL_WINDOWID hack, causing the
IDirectInputDevice2_SetCooperativeLevel call to fail.
This is a small patch to SDL_dx5events.c v1.21 that fixes the problem by
retrieving a handle to the root-level ancestor of the current SDL_Window and
passing that handle to IDirectInputDevice2_SetCooperativeLevel.

Subject: [Fwd: Re: SDL_image on Solaris x86 help please]
apparently __i386__ is insufficient for Suns C Workshop compilers...
so a sun x86 user told me about this...and tested his own solution.
I think it wouldn't be a bad idea to add __i386 to the SDL_byteorder.h
so that it works for that compiler.
