Q3map2:

* shot down spammy warning about samplesize for lmsize<=128; -debugsamplesize to show
	* numBspModels ('brusmodels') stat emitting


Radiant:

misc...
	* filters toolbar (disableable)
	* fix: shift + m1 click in tex browser to open shader in internal/external editor;
		defaulted internal; focuses on wanted shader; correct opening/saving
	* fix: angles "0 x 0" autoconvert to angle "x" on transform (was getting deleted w/o a trace)
