- make smart-sizing work again which was killed in previous commits
- removed several unnecessary/ugly workarounds
- miscellaneous small fixes
- new feature: restore previous window position when toggling out of
fullscreen mode
- new feature: if /f is specified in combination with /smart-sizing:WxH
we run the session in the /smart-sizing dimensions scaled to full screen
Since several contributers in the past repeatedly made the error
to treat xfc->width and xfc->height as equal with the x11 window
width and heigth I've renamed these variables to sessionWidth and
sessionHeight.
* fixed crash on server-initiated desktop resize and fullscreen toggle with /gdi:sw
* implemented desktop resize for /gdi:sw
* check for availibility of XRender extension and show error messages if a setting would require it
* fixed compile error if xrender devel packages are missing
* fixed bug with server-initiated desktop resize in fullscreen mode
The X11 core protocol does not have support for selection ownership
notifications. Until now xfreerdp worked around this issue by always sending
a format list pdu to the server after sending the format data response pdu
which makes the server side think that the clients clipboard data has changed.
This workaround has some severe drawbacks:
* it causes unnecessary data transfers because even without local clipboard
data changes the same data is always re-transferred over the channel
* with some clipboard managers (in the server sessions) you will get massive
endless data transfer loops because these managers immediately request the
data on clipboard changes.
The correct (core X11) way would be polling for selection ownership changes
which must include the ability to detect changes to the TIMESTAMP target if
the selection owner did not change.
The alternative to the poll based approach is using the X Fixes extension in
order to get selection ownership notifications.
This commit adds support for the XFIXES solution and also moves the complete
clipboard related event handling from xf_event.c to xf_cliprdr.c
