20af7b69	08/24/2016 09:31 PM	Leszek Koltunski	Correct an important bug in the vertex shader. b = 1/a if a!=0, 1 otherwise was incorrectly computed as b = 1.0 / (a+1.0-sign(a)). This, when 0<a<2^-24, suffers from 'round-off error': then a+1.0 = 1.0 (sic!) thus b = 1/0 !. Correct way: b = 1.0 / ( a - (sign(a)-1.0) )

77fcb24d	08/11/2016 10:41 PM	Leszek Koltunski	Fix for Bug #17: Regions of Fragment Effects migrate. Fix is: don't send vertex position and the Fragment Effect region to the fragment shader already multiplied by the ModelView matrix (that introduces the imprecise interpolation because of the projection effect) but simply send both of them in local coords.
