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
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...
* doubleClick/Enter in Entity inspector Class list = convert entities
* ctrl during creating brush = cube brush
misc...
* on worldspawn entity create/convert to one do most expected move-selected-primitives-to-worldspawn
* convert point entity to group one = placeholder brush at origin + remove origin key
* convert group entity to point one: set origin key to contained primitives center
* fix uniform rotation operations for eclassmodel, miscmodel entities
* scale miscmodel entities uniformly
* added func_detail to world and detail filters
* region->set_xy: using active projection, not just xy one; is subtractive (no region off before applying)
* new brush prefab: icosahedron
* refactored CSGTool, improved Hollow::diagonal algorithm stability
