/* XXX Too sleazy? WIN_GL_InitExtensions looks for certain OpenGL
extensions via SDL_GL_DeduceMaxSupportedESProfile. This uses
SDL_GL_ExtensionSupported which in turn calls SDL_GL_GetProcAddress.
However SDL_GL_GetProcAddress will fail if the library is not
loaded; it checks for gl_config.driver_loaded > 0. To avoid this
test failing, increment driver_loaded around the call to
WIN_GLInitExtensions.
Successful loading of the library is normally indicated by
SDL_GL_LoadLibrary incrementing driver_loaded immediately after
this function returns 0 to it.
Alternatives to this are:
- moving SDL_GL_DeduceMaxSupportedESProfile to both the WIN and
X11 platforms while adding a function equivalent to
SDL_GL_ExtensionSupported but which directly calls
glGetProcAddress(). Having 3 copies of the
SDL_GL_ExtensionSupported makes this alternative unattractive.
- moving SDL_GL_DeduceMaxSupportedESProfile to a new file shared
by the WIN and X11 platforms while adding a function equivalent
to SDL_GL_ExtensionSupported. This is unattractive due to the
number of project files that will need updating, plus there
will be 2 copies of the SDL_GL_ExtensionSupported code.
- Add a private equivalent of SDL_GL_ExtensionSupported to
SDL_video.c.
- Move the call to WIN_GL_InitExtensions back to WIN_CreateWindow
and add a flag to gl_data to avoid multiple calls to this
expensive function. This is probably the least objectionable
alternative if this increment/decrement trick is unacceptable.
Note that the driver_loaded > 0 check needs to remain in
SDL_GL_ExtensionSupported and SDL_GL_GetProcAddress as they are
public API functions.
