Updating the Prim Ref page

[Gerald Lasser]

My thoughts

-> first of all, the crosshair colours are wrong (ever since) blue is Z, red is X axis, that need to be brought in line

-> a link to a tutorial for the generation of ciscular prims (especially tori, mixed mode tori)

-> lo-res, Fast Render prims: document them as well? Imho the requirement for the stud2 needs to be documented with a sample imho

-> document depreciated naming (affects some round prims, e.g.  cylc2, cyli2, ccyli)

-> there are some circular prims where the prim substitution is not yet working in LDView: e.g. cylh, edgh

How shall we structure this?
- general geometry
  - rectangular
  - round
    - circle padding and adapters

- studs
  - system/duplo/primo
    - top
    - bottom
    - fillets

- technic
  - tooth
  - npeghol
  - connectors
  - bushes
  - axle holes (including a "how to pad")

- clips and handles

- minifig

- Joints and Hinges
  - Ball joints
  - Rotation joint 2 and 3
  - Click Hinge
  - Hinge

- duplo

- znap

Apart from the prims, may be we shall also document some special subpart, like screws and electrical parts (non Lego parts, lile batteries etc.)
