Touchscreen is present on Linux phones and can be present on generic Linux.
Allow to configure it in touchpad mode. Think of Raspberry pi connected to
a touchscreen
Stopping throws an exception when the audio track is not initialized.
Releasing is what we want: it stops the track, ignores the error and do
more cleanups.

ScummVM is optimised to render frames when something changes on screen.
As some host environments can perform poorly if the app does not
reliably refresh its output regularly (notably Steam overlay) this new
option ensures that Scummvm outputs a minimal amount of frames even if
nothing is changing in the game renderer.
Currently this is only implemented in the SDL OpenGL renderer.
The new config option is called force-frame-update and it takes a
integer value representing the desired minimum milliseconds Scummvm
should wait before forcing a screen update/refresh. E.g: 50.
Note that the rendering system will not force a re-draw of a frame if
the app has rendered a changed frame within the desired minimum refresh.
Thus if the app is outputting 30fps and force-frame-update is set to
100ms (~10fps) then no duplicate frame will be shown (in theory).
As this is implemented in OpenGLSdlGraphicsManager::updateScreen()
OpenGLGraphicsManager::_forceRedraw has had its access changed to
*protected* so that it can be access by it's descendant. The reason this
has been done in OpenGLSdlGraphicsManager::updateScreen() is so
SDL_GetTicks() can be used to track the elapsed time. If it is useful
for other platforms using OpenGL to have this feature it could be
implemented within OpenGLGraphicsManager::updateScreen() provided a
suitable platform independent replacement for SDL_GetTicks() is used.
This would potentially be better as OpenGLSdlGraphicsManager checks
various other states when deciding if the screen should update.
- Use a SVG asset to allow for better scalability
- Make the controller visible when touching the screen
- Allow for oblique moving by placing finger between two directions
- Add more buttons on the center area of the screen (GUIDE, START, LEFT
STICK, RIGHT STICK) and simplify right area (only four buttons)
- Don't track all fingers, only the ones needed
- Cleanup now unused code
