The following data values in the EFI_SIMPLE_POINTER_MODE interface are read-only and are
changed by using the appropriate interface functions:
ResolutionX The resolution of the pointer device on the x-axis in counts/mm. If 0,
then the pointer device does not support an x-axis.
ResolutionY The resolution of the pointer device on the y-axis in counts/mm. If 0,
then the pointer device does not support a y-axis.
ResolutionZ The resolution of the pointer device on the z-axis in counts/mm. If 0,
then the pointer device does not support a z-axis.
LeftButton TRUE if a left button is present on the pointer device. Otherwise FALSE .
RightButton TRUE if a right button is present on the pointer device. Otherwise
