Override OnImagesChanged() to call UpdateImageListIfNecessary() even in
wxGenericTreeCtrl for now, although in the future it would really make
sense to stop using wxImageList in its implementation and just use
wxBitmapBundle directly instead.
wxMSW is the only one which really needs an image list, as it's required
by the native control.
Also update the sample, even though it doesn't look very nice because
its icons are only available in a single size, so we have to always
scale them.
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.
This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.
There are no longer any qt headers included in wx/qt headers.
Applications do not need to link with qt librarys anymore, only wxqt libraries.
wxWindow and derived widgets only contain one pointer to their qtwidget, no longer
carrying both base and derived pointers in parallel as was before.
This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.
