Revision 14894 merged from apricot

----------------------------------
Arith:
	- axis angle to quat conversion function
	- short to float / float to short normals conversion function (eventually, we could go over the go and replace copy/pasted code everywhere)
	- ray triangle intersection (to complement the line triangle intersection function)
	
View:
	- viewray / viewline (get near plane point under mouse and ray normal/far point)


Particles:
	- extract viewline from brush_add function
