Subject: Add kbd_mouse_has_absolute()
X-Git-Tag: TizenStudio_2.0_p2.3~5329
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2a56b553ad972d323e3866b351d33072ff0ea49b;p=sdk%2Femulator%2Fqemu.git

Add kbd_mouse_has_absolute()

kbd_mouse_is_absolute tells us whether the current mouse handler is an absolute
device.  kbd_mouse_has_absolute tells us whether we have any device that is
capable of absolute input.

This lets us tell a user that they have configured an absolute device but that
the guest is not currently using it.
