(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

pivot control point and lines: ctrl = snap hard to face vertices and grid
grid density controls: shift = change density of both axes synchronously, ctrl = power of two grid
scale lines: shift = scale axes synchronously, ctrl = snap hard to vertices
alt + m1 on grid = skew texture (is possible alright in BP and Valve220 map formats, not in AP); ctrl = snap hard to edges
texture move: shift = only move along the axis with the biggest move, ctrl = snap grid lines hard to vertices and pivot
rotate: shift = rotate with step of 15 degrees, ctrl = snap hard to edges
* change freelook move speed units to game units; expand range; simplify
* print speed values on change by CameraSpeedDec/CameraSpeedInc commands to console
misc...
* draggable renderable transform origin for translate, rotate & scale manipulators
click w/o move = reset
move is constraintable to axis with shift pressed
* highlight manipulators' renderables on mouse hover
* mouse_moved_epsilon system (0.5% of viewport size) for m1, tunnel selectors, manipulators (except freelook) to make them more fail-safe
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
