INT 33,1A - Set Mouse Sensitivity



	AX = 1A
	BX = horizontal coordinates per pixel  ( 100)
	CX = vertical coordinates per pixel  ( 100)
	DX = double speed threshold


	returns nothing


	- sets mouse sensitivity by setting the ratio of the mouse
	  coordinates per screen pixel
	- provides same results as calls to both INT 33,F and INT 33,13
	- these values are not reset by INT 33,0
