I've been working some more on the raysnail, lots of basic 
infrastructure to do, little to show. I could extend the compatibility 
with PovRay scene files a little bit, CSG intersections and differences 
are supported now, even if only with two objects each.

The translate operation should work, rotate only for the y axis (the 
other two axes soon to be supported too).

The parser now supports finish blocks, but only reads the reflection 
item from it, the basic variant with just a float.

The attached render was created with this SDL file:

... it now supports PovRay SDL syntax to translate, rotate and scale 
objects, and the 10 parameter quadric object type. I still have to work 
on regular cone and cylinder SDL support.

And again, some more work done. The raysnail got better at 
transformations and CSG operations, and it now also supports PovRay SDL 
#declare and #while directives. One cannot #declare everything yet, that 
PovRay allows, but scalar values, vectors and object definitions are 
supported now.

Attached, there an example of a while loop. It was created by this SDL file:

https://github.com/Varkalandar/raysnail/blob/a2e24b1845f6686684b5e08b5e0106648b7aa7b0/sdl/declares.sdl

While I'm quite happy with the results, I think there is still about 90% 
missing to really render existing PovRay scenes with the raysnail.
