That's exactly what I meant -- emulation.  On MS-Windows, panning
generates horizontal and vertical scroll messages (as if the user used
the scroll bars), zooming generates Ctrl+mouse-wheel, taps generate
mouse clicks, pressing and holding generates a right-click mouse
event, etc.  The only gesture that doesn't get any emulation is
rotation, AFAICT.  See

for the details.  I assume X can do something similar, it would be
silly not to.
