Good idea. But do that only if ‘x-display-monitor-attributes-list’
returns more than one monitor so we do not needlessly loop in (and
possibly compromise) the one monitor case. Or (tediously) assign
+ min_x = XINT (Fnth (make_number (1), geometry));
+ min_y = XINT (Fnth (make_number (2), geometry));
+ max_x = min_x + XINT (Fnth (make_number (3), geometry));
+ max_y = min_y + XINT (Fnth (make_number (4), geometry));
only if the subsequent test
+ if (min_x <= *root_x && *root_x < max_x
+ && min_y <= *root_y && *root_y < max_y)
would succeed.
There's no guarantee that ‘x-display-monitor-attributes-list’ works on
all systems, especially on those where neither Xinerama nor XRandr are
installed. IIRC older versions of the latter might also have problems
when a monitor is added/removed during a session. The fallback should
always give the same results as the present code, but who knows ...
And just to make sure: Can we rely on the fact that XQueryPointer always
gives reliable results with multiple monitors and its present arguments?
