I made a video driver GAPI/RAW for WinCE (SDL-1.3).
RAW mode has a priority, and also, GAPI mode works with environment
"SDL_VIDEO_RENDERER=gapi" and for RAW mode "SDL_VIDEO_RENDERER=raw".
I checked the work on the screens of VGA, WVGA, QVGA, WQVGA, HVGA,
+ tested all modes with WindowsMobile Emulator.
Also, correctly draws the pointer position and the scale of the pointer
for VGA/WVGA modes,
correctly draws top left position for DM orientation screen, and
portrait/landscape/square geometry the screen also correct.
Also, I added a small fix for GDI fullscreen mode.
Patch for latest revision SDL-1.3 in an attachment.
Also added small path for mingw32ce build.
Fixed a bug where only mouse wheel up was sent on Mac OS X
Fixed a bug where mouse window focus was getting hosed by the fullscreen mouse code on Mac OS X
For some reason, having lpfnWndProc=DefWindowProc during window class registration causes IME input to not work in windows.
With this small change, IME input should now work in SDL windows but not in fullscreen mode.
* Switched event type to enum (int32)
* Switched polling by mask to polling by type range
* Added SDL_RegisterEvents() to allow dynamic user event registration
* Spread events out to allow inserting new related events without breaking binary compatibility
* Added padding to event structures so they're the same size regardless of 32-bit compiler structure packing settings
* Split SDL_HasEvent() to SDL_HasEvent() for a single event and SDL_HasEvents() for a range of events
* Added SDL_GetEventState() as a shortcut for SDL_EventState(X, SDL_QUERY)
* Added SDL_FlushEvent() and SDL_FlushEvents() to clear events from the event queue
The arrow keys and keypad arrow keys have almost the same scancodes!

Give the foreign window message proc more control over Windows events.
This may need to be adjusted when we add the capability for the app to specify whether it wants SDL to handle input for the window or not.

I noticed in trunk/SDL/src/video/win32/SDL_win32events.c, in this code here...
... if the device handle isn't found in mice[], which it won't be if
the mouse was plugged in after SDL_Init, then you end up with an
uninitialized value in index, which is then passed to various
SDL_SendMouse* functions.

I have prepared a set of patches to readd WindowsCE support to SDL 1.3.
I've created a new GAPI/Rawframebuffer and a DirectDraw renderer.
Both renderers are work in progress and there are several unimplemented
cases. (Notably
RenderLine/RenderPoint/RenderFill/QueryTexturePixels/UpdateTexture and
texture blending )
Nevertheless I am successfully using these renderers together with the
SDL software renderer. (On most devices the SDL software renderer will
be much faster as there are only badly optimized vendor drivers available)
I send these patches now in this unpolished state because there seems to
be some interest in win ce and someone has to start supporting SDL 1.3
Now on to the patches:
wince_events_window_fixes.patch
fixes some wince incompatibilities and adds fullscreen support via
SHFullScreen. NOTE: This patch shouldn't have any side effects on
Windows, but I have NOT tested it on Windows, so please double-check.
This patch doesn't dependent on the following ones.
wince_renderers_system.patch
This patch does all necessary modifications to the SDL system.
- it adds the renderers to the configure system
- it adds the renderers to win32video
SDL_ceddrawrender.c
SDL_ceddrawrender.h
SDL_gapirender_c.h
SDL_gapirender.c
SDL_gapirender.h
these files add the new render drivers and should be placed in
src/video/win32
Some notes to people who want to test this:
- I have only compiled sdl with ming32ce, so the VisualC files are not
up to date
- As mingw32ce has no ddraw.h this file must be taken from the MS SDK
and modified to work with gcc
- I had to modify line 2611 in configure.in to
EXTRA_LDFLAGS="$EXTRA_LDFLAGS -lcoredll -lcommctrl -lmmtimer
-Wl,--image-base -Wl,0x10000"
otherwise GetCPinfo wouldn't link. If someone knows whats causing this
I'd be happy to hear about it.
It would be great if these patches could make their way into SVN as this
would make collaboration much much easier.
I'm out of office for the next week and therefore will be unavailable
via email.
Regards
Stefan

From: Stefan Klug
Subject: [SDL] SDL 1.3 WinCE backend
as promised, I've started to work on the WinCE backend of SDL 1.3
I've modified the win32 video backend and the gdi renderer, to work
properly in WinCE.
The results till now are great, but there is still some work to do.
Attached are two patches with my changes.
I would be happy if someone could review and propably commit them.
The first one (configure.in.patch) should be straight forward without
any side effects.
The second one does the necessary changes to the win32 backend. I was
really unhappy to start slicing this shiny new backend with
#ifdef/#endif but I saw no other option.
The most problematic issues are:
- WinCe has no GetDIBits, so its practically impossible to fill a
BITMAPINFO with correct values. I therefore removed the bmi member from
the GDI_RenderData in SDL_gdirender.c to prevent usage of a not or not
properly initialized bmi.
- In SDL_win32window.c I exchanged some ASCII function by their general
counterparts, (In CE only the Unicode versions are available). I don't
know if this has a negative effect when running in win32
Cheers
Stefan

Subject: [SDL] Critical SDL 1.3 patch
Displaying a window created with SDL_CreateWindowFrom was causing stack overf
lows for me under certain conditions. After far too much work trying to get
Visual Studio's debugger to play nice with a program written in Delphi, I tra
cked it down to a nasty reentrancy cycle in the WndProc handling. Here's a p
atch that fixes the problem

The screensaver is disabled by default when using SDL 1.2 compatibility.
Use the new XScreenSaver extension, removed unused DPMS extension.

Fixed setting the mouse focus when the mouse enters/leaves the window.
