navigation while drawing

[tmpvar]

Sometimes it is useful to look at the features around the current drawing. As it stands right now, we setup a draw plane to catch raycasts from the unprojected mouse coords. This limits how big the drawing can be.

potential solution 1

don't bother with the plane and instead get more clever with the mouse(down/move/up) events. If the user wants to rotate the scene they are going to down->move->up which should be ignored by draw. If the user does a down->up then draw projects the point onto the plane and uses that.

other thoughts are welcome

Pending the solution to this problem, there is a bug with the plane orientation that I'm going to punt on for now:

potential solution 2

Make the DrawMode ignore mousedown events when a draw plane is already defined. Events should flow into the default navigation mode and rotation should work as expected.

If you are in line or other drawing mode, clicking/dragging will get intercepted by the mode and it will just work.
