Subject: [PATCH] Michael Bicha to Sam

I came across further issues with SDL 1.2.14 on win32 in combination
with touch screens.

When you touched the screen older SDLs reported
SDL_MOUSEMOTION to the touch position
SDL_MOUSEBUTTONDOWN at the touch position

1.2.14 reports
SDL_MOUSEBUTTONDOWN at the last mouse position before the touch
and then a
SDL_MOUSEMOTION to the touch position

I found that to fix it in the file SDL_sysevents.c i had to put back the
following lines from 1.2.12 to get it working correctly again:
               if ( mouse_relative ) {
               /*    RJR: March 28, 2000
                   report internal mouse position if in relative mode */
                   x = 0; y = 0;
               } else {
                   x = (Sint16)LOWORD(lParam);
                   y = (Sint16)HIWORD(lParam);
#ifdef _WIN32_WCE
                   if (SDL_VideoSurface)
                       GapiTransform(this->hidden->userOrientation,
this->hidden->hiresFix, &x, &y);
#endif
               }
               posted = SDL_PrivateMouseButton(
                           state, button, x, y);

where there was only
               posted = SDL_PrivateMouseButton(
                           state, button, 0, 0);
in 1.2.14 (appx. line 484)

please feel free to put that change into any SDL lib you like in any way
you like and thanks for your great work !
