notes:
was okay in windows
wnd position is not preserved on hiding via Close event now, requires extra handling, as in class RotateDialog or g_guiSettings (no much critical cases exist)
min max buttons aren't shown (when requested) in Ubuntu, shown in Windows; were shown for Qt::Window flag
misc...
* entity inspector, entity list->'autofocus on selection' buttons: also do FocusAllViews() on clicking them
* focus on preferences treeview on 2nd+ call to make text search to work
* fixed WindowPositionTracker globally: minus many particular hacks, plus correct wnds positioning in Floating viewports layout
* fixed ToggleShown functionality: shown/hidden wnds states are saved and loaded correctly in Floating viewports layout
* also save/load XY and Cam viewports visibility states
* new preferences->layout icons
* fix: stop chaseMouseMotion on mouse button release
disable fastnormalize for light: was increasing dirt from arealights, lighting with acute angle
Radiant:
binds...
* QE tool: alt + m1 drag in primitives mode:
click face = clicked faces shear
* m3 in texbro: select texture w/o applying to selection
* `: XYFocusOnSelected
* ctrl + shift + e: Select Connected Entities
misc...
* search in shortcuts list
* edit shortcuts on m1 dbl click
* edit shortcuts fix: could highlight a few rows for editing
* texbro: toggle off hideUnused on loading a tag
* fix of: undo something, select tex in texbro, no redo available
* epsilon in resize brush selector to prevent perpendicular faces pickup
* clone group entity primitives to separate entity on cloneSelectedMakeUnique
* Focus on Selected option in Entity List (focus cam and center xy)
* entity inspector: connected entities walker (select target / targeting / both)(focus)
