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
by removing not needed anymore update_move_planepts_vertex code
* disable points snapping to .125 grid during edge manipulation (already disabled for vertex mode)
* 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...
* 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
misc...
* experimental fix of rendering scene and evaluating brush/patch representation TWICE on every transform (literally after every mouse move fraction)
misc...
* new texture lock algorithm for BP map format, supporting any affine transformations
* more robust texture lock algorithm for AP map format, locking what is possible to; also improves seamless face2face tex paste function
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...
* ctrl + shift + m3/drag: project tex from face in tex clipboard to brushes(BP format) and curves
misc...
* fixed and improved normal finding in patch texture autocap algorithm
* removed axis cycling in patch cap texture; using autocap
* patch cap texture: project, using brush texture projection math of current mapformat to make it seamless with brushes by default
* Surface inspector->Project functions work for curves (in AP map format too)
