logic: load 6 skybox textures when shader gets used by scene, don't unload dynamically, just on 'flush'
texture browser only uses normal preview image and doesn't trigger potentially heavy box loading
also fix R_ResampleTexture for [2+x upscaling
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
don't crash on bsp w/o vis
don't crash with origin in the void (includes inside of structural brush)(do reset)
grab point to analyse from camera position with nothing selected; grab from any objects selection too
fix rendering issues
read surfaces written by q3map2 correctly + faster rendering code
print number of loaded drawsurfaces to console for evaluation of optimization done
fix a couple of of leaks and crashes after new/delete
* Valve220: Project {axial, ortho, cam, from face} functions
* conversions between AP, BP and Valve220 brush types; conversions to Brush Primitives and Valve220 formats are lossless
* detect brush format and automatically convert to current one on map Import and Paste
* Valve220: fixed Reset function, implemented Rotate one
* Valve220: fix overwriting basis on brush clone/map import ( in Face( Face ) constructor )
* BP: fix: normalize shift values during import, arbitrary projections and face->fit
* Valve220: fix texture lock for scaling, fix for negative texdef.scale
* brush format is preference for [maptypes, brushtypes]: [mapq1, quake], [mapq2, quake2], [mapq3, quake3]:
preferences->Brush->Brush type: Axial projection, Brush primitives, Valve 220
* autodetect brush type on map opening
* brush face surfaceflags are optional on loading for flexibility
* 'Snap planes to integer grid' option is always off by default
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...
* selection system: fixes of: selecting point behind point (not perfectly precise distance)
selecting occluded objects and faces via direct and indirect hits
* select models from back in 2d
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
misc...
* fix scaling for doom3 brush format
* Pointfile function: try to also load .pts leak line file (q1), if .lin isn't found
* snap transform origin for flip commands
* change light intensity save format from %f to %g to prevent .99999 on transforms
* support 'stupid quake bug' (invert pitch in angles)(generic and miscmodel ents)(cfg: entities="quake" in .game)
* clipper: place 1st and 2nd points far, 3rd near to ease 3 points clipping
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
