allows most of file types with non lowercase extension
known issue: textures with non lowercase extension in loose folders are visible now, but they aren't loaded, because it leads to fopen( filename.lowercase_extension )
(symbols rendered to atlas texture)
deliver position via glRasterPos + glGet GL_CURRENT_RASTER_POSITION to avoid adding calculations of screen coords in many spots
solves problem: pango 1.44 switch freetype->harfbuzz = bitmap fonts aren't available, in particular no gdk_gl_font_use_pango_font()
text is rendered from font bottom (was from baseline)(latter is wanted less often)
wgl bitmap<->pango sizes do not match, thus realign all text positions, increase default font size
make 2D axes labels, view type text, sizing info adaptive to font size

m1 = assign model to selected entity nodes (shift + e to select nodes of group entities)
m1x2 = insert "misc_model" with given model
m1 drag = rotate model
Preferences.Model Browser: list of * separated folderToLoad/depth values, e.g. *models/mapobjects/99*maps/1*; */99* loads root
* 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
binds...
* shift + m3: apply texture name and alignment to selected primitives and faces (m3 was inconsistent + often required quite deep planning)
* ctrl + shift + m3: also project tex from face to selection
misc...
* lazy cursor updates in clipper mode
* update cursor immediately on clipper mode toggles
* fixes and optimizations of entity names rendering; for instance: don't prerender textures for unneeded names
FBO overlay fixes
