I have one small feature request. To be able to enlarge the magnification window, perhaps by some set sizes or using keypresses like Control + '+' (i.e. increases window size by some increment or selects next set size).
yes, the cursor mouse movement was not 100% accurate.
Sometimes one press was lost.
This depends on mouse_event_(). With relative moves it uses the mouse driver
and his acceleration function and that stuff.
So I decided to use the absolute setting of the position.
I also switched from mouse_event_() to SendInput_(), since mouse and
keyboard_event are marked as deprecated.
So it is also a good example for mouse control with SendInput_()
