Improve Path Editing

[Robert42]

• [x] Visualize the Path
• [x] Allow modifying path
  • [x] Allow inserting keypoints between already existing keypoints instead of appending to the end
  • [x] allow removing keypoints

It would be nice to see the camera path. Maybe, something along

glLineStipple( 1, 0x5555 );
glLineWidth( 5.0 );
glEnable( GL_LINE_STIPPLE );

added to the list :)

Merged into develop with af8a322fc3acb31b7a5d9fabc9e855e0dddc9ed

glLineStipple is sadly deprecated in OpenGL 4.5. Emulating its behavior with a fragment shader is possible, but I think there are others issues with a little higher priority. If you still prefer having stipples, I can open a new issue for them ;)

It is not about the glLineStipple. It is more about visualizing the camera trajectory.

[Robert42]

ok, that's already in the develop branch :)

[PatWie]

Yep, saw and tested that.
