[Feature Request] Ability to ignore (or remap) mouse buttons

[ejelly]

Trackpads often treat short taps as left mouse button clicks, and long presses as right mouse button clicks. While this is pretty good for “desktop” use, in games where you need relatively precise control over the location of the mouse pointer I frequently end up accidentally triggering the right mouse button long press, because trying to adjust the mouse pointer with small deltas is misinterpreted as a “press”.

Instead of having to disable the long press globally (and outside of dosbox-pure), it would be nice if dosbox-pure could just ignore the right mouse button click, and just not pass it along to the dosbox. If I still need right clicks in the game, I can still map something else to right click (and this part already works, there’s just no option to ignore an actual right mouse click as far as I can tell).
