screencast: Fix transform_position(), when using fractional scaling

Browse Source 
Commit 64c9c9c5b0 fixed monitor
screencasting, when fractional screencasting is enabled.
For the remote desktop usage, NotifyPointerMotionAbsolute() submits
the new mouse pointer position in addition to the stream, where the
mouse pointer was moved.
When not using fractional scaling, the mouse pointer position is
correct.
With the usage of fractional scaling, the mouse pointer position is
wrong, as the scale of the position is applied two times.

Fix this behaviour, by reverting the second scale by dividing by the
logical monitor scale, when fractional scaling is used.
