Add a safety net X11 error handler, to reset the vidmodes before crashing.

Fixed bug 1579 - Creating a texture with unsupported format may cause double-destruction Alexander Hirsch 2012-08-25 20:01:29 PDT When creating a SDL_Texture with unsupported format (I'll now refer to it as texture A), SDL_CreateTexture will call SDL_CreateTexture again with GetClosestSupportedFormat to set texture->native (which I will now refer to as texture B). This causes texture B to be put before A in renderer->textures. If texture A is explicitly destroyed, everything is fine. Otherwise, upon SDL_DestroyRenderer, the loop will first encounter texture B, destroy it, then texture A, destroy that which will want to destroy texture->native and since it is already destroyed set an error. The solution could be as simple as swapping texture A with B after texture->native gets set in SDL_CreateTextures.

Fixed bug 1605 - SDL_DestroyWindow causes erroneous error message You can't pass a NULL window into SDL_GL_MakeCurrent()

Clear the queue active flag when we shutdown, so we don't have a mutex error trying to read the queue.

Fixed bug 1584 - Improved glError checks in the opengl renderer Martin Gerhardy 2012-08-27 02:42:25 PDT I've extended the gl error checks. This is needed because on my system there are errors in the renderer that are hard to find. Also glError can return multiple errors. Even if SDL_SetError would only contain the last one of course, the SDL log facilities are able to get the output for each error.

Made it clear that locking a streaming texture is a write-only operation.

Fixed bug 1587 - "aclocal" fails to generate a sufficient "aclocal.m4" Cecil Curry 2012-08-27 16:55:12 PDT Allow "aclocal" to find the "AC_CHECK_DEFINE" macro. On running: rm aclocal.m4 libtoolize --install --copy --force aclocal -I acinclude autoconf -I acinclude The former three commands succeed, but "autoconf" fails with: configure.in:198: error: possibly undefined macro: AC_CHECK_DEFINE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. "aclocal" fails to find AC_CHECK_DEFINE and hence add such macro to "aclocal.m4". Here is why: * "acinclude/ac_check_define.m4" defines AC_CHECK_DEFINE via define() rather than AC_DEFUN(). * "aclocal" fails to find macros defined via define().

Fixed memory leak in an error case

Fixed bug 1496 - SDLView not created for a Cocoa window, resulting in missing right mouse clicks When you create an nswindow it automatically gets a default view, so we'll just create an SDLView if we're creating the window.
