FS#12 - facets pattern in normal map

Using a facet pattern in a normal map results in a unspecified error in Evaluate_TPat at the render stage.
This probably should be caught at parse time to give a more descriptive error and a line number.


sphere {
  0, 1
    pigment{rgb <1,1,1>}   
    normal {
      normal_map {
         [0 bumps ]
         [0.5 facets ]
         [1 bumps ]

Tested with official 3.7RC6: fine, error line is correct, message seems clear.

Confirmed with beta.32 based development version.

Note that the offending construct is “facets normal_map {...}”, not the “facets” statement appearing inside the normal_map block (which can be replaced with e.g. “bozo” with the same effect).

Also note that the render-time abort matches behavior of version 3.6.

What is the status of this?

nothing new from my side; Chris?

I took the liberty to “steal” this task from Chris, and fix this with change #5610 as suggested.
