[M3devel] LONGINT -> more bugs in m3tk

[Daniel Alejandro Benavides D.]

Hi all:
This is good news (though old) shows up, this is perhaps the problem with Obliq problem (worked in pm3), by the way what could be missing if so from there in CM3? 
Thanks in advance

PS It might be that CM3 once worked Obliq, since there is a thesis reportedly working on Obliq3D of Blair MacIntyre, an augmented reality system, this is probably 1999, so a lot of stuff might came or not after that.
