Feature request: initial cursor position in globals

[ajwood]

It'd be great to be able to control the initial cursor location from the globals file

@ajwood take a look at this implementation and see if it does what you need.

@rdvincent this definitely gets the job done! Thanks! I noticed a couple things though:

1. it only works if all three dimensions are specified
2. IF Initial_volumes_synced=true
   AND Initial_volume_1_world_x/y/z are set
   AND Initial_volume_2_world_x/y/z are unspecified,
   THEN volume 2 internal defaults sync and destroy those specified for vol1 in the globals.

Probably not critical, but might be confusing for a naive user.

[rdvincent]

I can certainly make it work if the user only specifies the Z direction, e.g. The other directions would just be set to the default.

The second case is more confusing. I will have to think about how that should be handled. Perhaps I was incorrect to create two different initial positions, and the initial position should automatically apply to both volumes.

[ajwood]

1. Is Z just an example? Would it also work if only X or only Y was specified? Leaving it the way you have it is probably fine too though; would it be possible to issue a warning if any of the three are missing?

2. Agreed on messiness. I think this might work at the vol2.position initialization though:

IF synced AND vol2.position == FLT_MAX:
THEN vol2.position = vol1.position

Does that look right to you? Would it fit cleanly into the code?

[rdvincent]

1. We can absolutely make it possible to set only any one (or two!) of the axes and let the remaining axes use the defaults. I was just being paranoid in requiring all-or-nothing behavior, to avoid situations where a typo causes 2 of 3 to be correct. But we warn about unknown globals, so not a big deal.

2. I'll give this some thought, but what you suggest should be an improvement, although I hope this is a rare edge case!

[ajwood]

Whatever you like - thanks!

@ajwood Try this version out - here's how it should behave:

1. Specifying any axis will set the initial position. Unspecified axes default to world position zero.
2. If Initial_volumes_synced is TRUE, the following behavior is used:
   a. If volume 1 position is set, use it for both volumes.
   b. Else if volume 2 position is set, use it for both volumes.
