Q3map2:

Q3map2:
	* -backsplash (float)scale (float)distance: scale area lights backsplash fraction + set distance globally
		(distance < -900 to omit distance setting); def = 1 23; real area lights have no backsplash (scale = 0)
		q3map_backsplash shader keyword overrides this setting

Radiant:

binds...
	* alt + m1 click/drag in component modes: select objects
misc...
	* fix: selected entity and brush numbers display in 'Find brush' dialog
	* prefer to display texture width and height in status bar over name (PANGO_ELLIPSIZE_START)
	* allow search shortcut (ctr+f in win) in entity inspector -> entity class list
	* fix: don't save empty group entities (but worldspawn)
