Use the SDL safe strcpy() function

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 :-)

When querying the display size for a fullscreen window, the display size is the size of the fullscreen video mode.

Depend on XRender version 0.10 or above and XFixes version 2.0 or above. Moved these dependency checks into CheckXRender() and CheckXFixes().

Add support for texture modulation (both color and alpha). testsprite2 works now with --cyclealpha and --cyclecolor.

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.

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

I also found a bug in the non-printable character fix.
In SDL_keyboard.c:SDL_SendKeyboardText:
    if (*text < ' ' || *text == 127) {
needs to be:
    if ((unsigned char)*text < ' ' || *text == 127) {

Otherwise bytes >= 128 will be considered non-printable.
