scad_render_to_file forwards file_header

[Exr0n]

Update scad_render_to_file to forward file_header to scad_render, to maintain the interface of SolidPython.

I believe this is the correct fix to re-enable the scad_render_to_file(scad_obj, 'filename.scad', '$fn = 50') to increase the resolution of rendered curves like cylinders?

There is one mention of $fn and segments in the readme, but I couldn't figure out how to use it.

You can set the global $fn like this:

>>> from solid2 import *
>>> from solid2.extensions.greedy_scad_interface import set_global_fn
>>> 
>>> set_global_fn(72)
>>> cube() #test it
$fn = 72;
cube();

Take a look at the greedy_scad_interface there are more functions in there to manipulate global variables.

I though I -- at least wanted to -- completely wiped out the file_header parameter while refactoring that module, but apparently I didn't and ended up with an inconsistent api....

So, thx a lot for this issue and the corresponding fix!

============ back to global $fn ===========
Actually you don't need to explicitly import the greedy_scad_interface_extensions it's enabled by default, so calling set_global_fn is what you want.

And I see the issue concerning the docs. Since I consider the examples as docs, I guess the underlying issue is that this functions should not be mentioned the first time in the very last example.... I'll have a look at it, if you have any suggestion, let me know!

fixed the docs issue, it's now mentioned in the very first example :D
