Summary	0001315: Add line to POV-Ray Camera to Set Automatic Aspect Ratio.
Description	Would like to see a line added to the camera section of the FreeCAD generated POV-Ray script that would automatically set the cameras aspect ratio to the width / height,(+Wn +Hn) that is set by the user in the View > Preferences > Raytracing. This would be to great advantage to both novice and experienced users alike. The current script looks like this. - `camera { location cam_location look_at cam_look_at sky cam_sky angle cam_angle }` With the addition of one line, any width / height entered will render the target item without distortion. The camera section should be. - `camera { location cam_location look_at cam_look_at sky cam_sky angle cam_angle right x*image_width/image_height //Auto Aspect Ratio }`
Additional Information	This was tested rendering a FreeCAD part with 4:3, 16:9, 2.35:1 (cinema) and 1:1 aspect ratios on POV-RAY 3.7. The line of code "right x*image_width/image_height" was taken from an example given for POV-Ray 3.6, so it should be compatible with all modern installs.
Tags	No tags attached.
