Sam Lantinga dcd17f5473 Renderer logical size is now implemented as a render target
This fixes rounding errors with coordinate scaling and gives more flexibility in the presentation, as well as making it easy to maintain device independent resolution as windows move between different pixel density displays.

By default when a renderer is created, it will match the window size so window coordinates and render coordinates are 1-1.

Mouse and touch events are no longer filtered to change their coordinates, instead you can call SDL_ConvertEventToRenderCoordinates() to explicitly map event coordinates into the rendering viewport.

SDL_RenderWindowToLogical() and SDL_RenderLogicalToWindow() have been renamed SDL_RenderCoordinatesFromWindow() and SDL_RenderCoordinatesToWindow() and take floating point coordinates in both directions.

The viewport, clipping state, and scale for render targets are now persistent and will remain set whenever they are active.

Sam Lantinga 9ff1055489 Workaround for Visual Studio 2019 const warning
Visual Studio 2022, gcc, and clang all agree that "const SDL_DisplayMode **" is a non-const pointer to const data, but Visual Studio 2019 warns about this, so we'll just add a cast to the SDL_free() call for now.

Apparently this was a legitimate bug that has been recently fixed:

Sam Lantinga 6b137579ea Windows default to fullscreen desktop mode if they don't pick an explicit video mode
Rather than iterating over display modes using an index, there is a new function SDL_GetFullscreenDisplayModes() to get the list of available fullscreen modes on a display.
{
    SDL_DisplayID display = SDL_GetPrimaryDisplay();
    int num_modes = 0;
    SDL_DisplayMode **modes = SDL_GetFullscreenDisplayModes(display, &num_modes);
    if (modes) {
        for (i = 0; i < num_modes; ++i) {
            SDL_DisplayMode *mode = modes[i];
            SDL_Log("Display %" SDL_PRIu32 " mode %d:  %dx%d@%gHz, %d%% scale\n",
                    display, i, mode->pixel_w, mode->pixel_h, mode->refresh_rate, (int)(mode->display_scale * 100.0f));
        }
        SDL_free(modes);
    }
}

SDL_GetDesktopDisplayMode() and SDL_GetCurrentDisplayMode() return pointers to display modes rather than filling in application memory.

Windows now have an explicit fullscreen mode that is set, using SDL_SetWindowFullscreenMode(). The fullscreen mode for a window can be queried with SDL_GetWindowFullscreenMode(), which returns a pointer to the mode, or NULL if the window will be fullscreen desktop. SDL_SetWindowFullscreen() just takes a boolean value, setting the correct fullscreen state based on the selected mode.

Sam Lantinga 324c0b76a0 Removed SDL_HasGamepads(), SDL_HasJoysticks(), and SDL_HasSensors()
Also cleaned up logic for whether we need to poll for events:
- We need to periodically poll for joysticks to handle hotplug.
- We need to frequently poll for joysticks and sensors when they're open so their state can be updated

Sam Lantinga 7f23d71b6a Added SDL_modf() and SDL_modff()
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;

/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;

/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
    ...
}

Sam Lantinga ea0c2f55be SDL API renaming: *Is* functions
Feedback from @icculus:
"IsTablet" uses "is" as a form of "to be" ...like, the actual question is of its nature.

The rest is just a superfluous word in the question and it flows as better English with if (RectEmpty) than if (IsRectEmpty)

Sam Lantinga 66351fd4ba Replace tri-state functions SDL_EventState(), SDL_GetJoystickEventState(), SDL_GetGamepadEventState(), SDL_ShowCursor()
`SDL_QUERY`, `SDL_IGNORE`, `SDL_ENABLE`, and `SDL_DISABLE` have been removed.

SDL_EventState() has been replaced with SDL_SetEventEnabled()
SDL_GetEventState() has been replaced with SDL_EventEnabled()
SDL_GameControllerEventState has been replaced with SDL_SetGamepadEventsEnabled() and SDL_GamepadEventsEnabled()
SDL_JoystickEventState has been replaced with SDL_SetJoystickEventsEnabled() and SDL_JoystickEventsEnabled()

SDL_ShowCursor() has been split into three functions: SDL_ShowCursor(), SDL_HideCursor(), and SDL_CursorVisible()

Sam Lantinga 16092f58bb Updated gamepad, joystick, sensor APIs, removing device indices
Instead of indexing into an internal list of devices which requires locking, we return a list of device IDs which can then be queried individually.
