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
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...
* place created simple patch mesh not in middle of bbox, but on edge to make result more usable
* prefs-interface-layout-single scrollable toolbar
misc...
* changed surface inspector behavior from 'set whole texture projection' to 'set modified value' (makes sense for multiple surfaces selected)
* BP: surface inspector and Tex* binds scale texture by its axes, not world axes
* BP: fix rotation of tex projection with scale S != scale T
* BP: fix ruining nonregular tex projections by surface inspector (for example after fit/seamless/arbitrary projection)
* jump over tex projection scale = 0 case, while modifying one (AP and BP)
