Subject: Adjust cursor position
X-Git-Tag: submit/tizen/20220427.130003~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dd08a4f0ffb60c294a5c862612c202315c04e6c9;p=platform%2Fcore%2Fuifw%2Fe-mod-tizen-rdp.git

Adjust cursor position

if there is a big difference between pointer position and rdp client cursor position,
adjust move value.
- no big difference : move = previous rdp client cursor position - current rdp client cursor position
- big difference : move = previous pointer position - current rdp client cursor position
