GitLab

* Requested by Bruce
* FIXME: ugly font (characters don't line up properly)

* Using variables as defined in Ben's formulas
* Using axes relations and rotation directions as defined in Ben's formulas

* Limit beam angle to 120 degrees
* Limit (inner) beam cone radius to 0 (if outer radius is less than rim size)

* Will be used to determine pulse profile (instead of freely moveable camera)
* Slightly reduced spin/magnetic axes to allow line of sight to overlap

* Interactive control via GUI (initial setting 20 degrees)
* Also: variable for beam length/height
* Also: variable for beam rim size (thickness)

* Removed binary features
  - Removed companion
  - Removed orbital planes
  - Removed pulsar mass
  - Removed semi major axis
* Using triangle fans and rims to contruct complex beam cones (instead of simple quadric)
* Using wireframe model instead of textures (better cone feature visualisation)
* Using lighting only for spherical pulsar shape (doesn't yet work for cones)
* Adjusted pulsar rotation axis to line up with wireframe poles
* Adjusted initial view to be in line with rotation axis (as requested by Ben)

* It's pointless anyway
* Avoids shortcut ambiguities

* JPG version fails to load on some Macs and on Windoze (static build)
* TODO: try alternatives to reduce the PNG size or fix the root cause
