Relative mode testing

See test program at the bottom of this file.

Initial tests:

• When in relative mode, the mouse shouldn't be moveable outside of the window.
• When the cursor is outside the window when relative mode is enabled, mouse clicks should not go to whatever app was under the cursor previously.
• When alt/cmd-tabbing between a relative mode app and another app, clicks when in the relative mode app should also not go to whatever app was under the cursor previously.

Code

#include <SDL.h>

int PollEvents()
{
    SDL_Event event;
    while (SDL_PollEvent(&event))
    {
        switch (event.type)
        {
            case SDL_EVENT_QUIT:
                return 1;
            default:
                break;
        }
    }

    return 0;
}

int main(int argc, char *argv[])
{
    SDL_Window *win;

    SDL_Init(SDL_INIT_VIDEO);

    win = SDL_CreateWindow("Test", 800, 600, 0);
    SDL_SetWindowRelativeMouseMode(win, true);

    while (1)
    {
        if (PollEvents())
            break;
    }

    SDL_DestroyWindow(win);

    SDL_Quit();

    return 0;
