support detachable menus in submenus of plugins menus
user_shortcuts_init() and user_shortcuts_save() are moved to not the most convenient spot, as init has to happen after plugins init and before menus creation
* fix: region() functions work for entities, having model, which is instantiated multiple times in a scene
* warn on Map_RegionBrush with none selected
* fix: 'region set brush' is deleting ultimateselected only (is using one to get bounds)
* deselect components on any region() function: could be texturized or edited implicitly
* allow 'region set selection' in components mode
* Map_RegionXY: deselect anything (could leave stuff selected + invisible)
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
misc...
* place created simple patch mesh not in middle of bbox, but on edge to make result more usable
* prefs-interface-layout-single scrollable toolbar
binds...
* m2 drag in cam = sideways+updownways strafemode; do not enter/quit freelook, if long button press (>300ms)
* m1 drag in freelook = sideways+updownways strafemode (mainly for visual editing)
* ctrl + m3/drag = seamless brush face to face texture paste; works for any faces in BP mode, only axial ones in AP
* ctrl + shift + a: select all visible brush faces and curves, textured by selected shader
(more obvious way, than existing ones: components mode::faces->shift+a and find/replace to empty)
* shift during creating brush = quadratic brush
* drag clipper point + shift = constrain to axis with biggest move amount
misc...
* -gamedetect command line option to enable game detection
* don't disable aero by default; -aero command line option disables one
* "Don't show" (during session) checkbox in Light Intensity dialog
* fix: show-grid toggle hides grid, when snap-to-grid is off too
* region mode: draw out of region part of grid in subtle style
texbro tags button png icon
menus...
* view->show->Entity boxes (always show bbox for ents with model)
misc...
FBO support
* preferences->display->entities->Names Display Ratio (2D): hide names, if view_size/bbox_size > value; def = 64
menus...
* Shortcuts item moved from Help to Edit
misc...
* fix: q1 mdl reader out of bounds reading crash
* fix: q1 mdl loading of MDL_FRAME_GROUP case
* fix: rightclick main wnd border, release in texbro glwidget == crash (unfreezepointer)
* texbro: search in currently shown textures
* ask for saving nonsaved map on project settings change
* func_detail to nongame group ents counter
* deiconify main wnd, unmaximize maximized view on app closing to save correct layout data
* close preferences dialog on ESC
* Enter = Ok in global and path settings dialogs
* print renderer stats in XY views too
* global 'show renderer stats' option, def = off
* ~10x faster opengl text rendering
