Non rectangular selection and other improvements

[TD3D Eidomatica]

Hello,

first of all congratulation for the software you develop, i propose some little but useful featurs to add to the software:
- a free selection (non recatngular) of the cloud points to clean in a easy way the cloud
- a x64 version
- Textures (as just said in this group)
- Some tips to scan in the best way ( i founded problems in every step of of the process, during the scanning somethimes it stops, during the point computation somethimes it stops, during the obj calculation somethimes it stops).

i'm sotty for mya english
