misc...
* restrict unwanted angle(s) keys commits on moving generic, eclassmodel, miscmodel entities
* reverted angle(s), origin, scale entity keys save format from %f to %g
* fix uniform rotation operations for generic entities with angles key
* use more precise meth for rotating point entities with only angle rotated
* snap tiny inaccuracies in angle(s) and origin point entities keys
* workaround: don't discard empty group ents, having origin key
* entity class convertion: prevent converting worldspawn; prevent converting point entity to empty group
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
misc...
* texbro: disable alpha transparency by def; isn't good in half of cases
* find/replace: tooltip helper note about search mode
* Entity: arrowheads, showing direction of connection-lines in addition to color-code; New algorithm: are visible in all orthogonal projections
* tweak: do not render 'misc_model' & 'light' entity names
* filters: patches: +filter ones with surfaceparm playerclip
* translucent filter also works for shaders with qer_alphafunc
* filter areaportal, if single face matches (allows case with other faces, using 'skip')
* filter translucent, if single face matches
* filter liquids by surfaceparm {water, lava, slime} in addition to textures/liquids path
