Describe the bug
According to Steffen, exporting edge lines to POV generates a syntax error in the POV:

Hi Travis, here is a small demo for the problem:

  • test.ldr is a small LDRAW scene, export it with LDView 4.5 with edges and cond edges export to POVRay enabled
  • result is the test.pov file containing the syntax error
  • I corrected the file by hand, the result is test_corrected.pov

The 4 manual corrections which I did are as follows:

  • removed stray #end line (syntax error)
  • wrapped the declaration of LDXEdges by #if (LDXSkipEdges = 0) ... #end because it otherwise takes HUGE parsing time in real-world scenes (which are MUCH larger than test.ldr)
  • wrapped the declaration of LDXConditionalEdges by #if (LDXSkipEdges = 0) ... #end because it otherwise takes HUGE parsing time in real-world scenes (which are MUCH larger than test.ldr)
  • corrected the #if logic:
#if (LDXSkipEdges = 0)
	object { LDXEdges }
	object { LDXConditionalEdges }
#end

I'd like to suggest to takeover these into LDView.
