Rotations are now stored internally as radians, while exposing degrees in the UI -
in the graph editor and UI controls. This is done in two areas:
1) Using the unit system to convert RNA data to display as degrees in the UI controls
2) FCurves now use degrees for rotation, so you can edit in the graph editor what
you see in the UI.
All rotation data is consistently accessible in DNA and RNA as radians, degrees are only
used for the UI controls and graph editor.
This commit includes conversions will convert old files (stored data and also fcurve data)
to the new units, hopefully everything should go smoothly!
Part of this also changes a few properties that were hard-coded as degrees before (such
as IK pole angle and brush texture rotation) to also use the same consistent system of
radians (dna/rna) and degrees (ui).
Thanks to Joshua for hints and review here too.
- BLF_lang_init used confusing IFDEF's, unlikely this was well tested. Split this into 3 functions for Apple/Win32/Unix, Unix uses BLI_gethome_folder(), cant test others, ideally they should use BLI_gethome_folder too but needs testing.
Possibly each os cant be made to use BLI_gethome_folder and the separate func's can be removed (please test).
- units, hectometers were displayed wrong.
- use the scene context for the unit settings since there isn't a better place for it currently.
- added 'chain' to imperial units
- set more rna props to be distances and angles.
long/short units...
day,d, hour,hr,h, minute,min,m, second,sec,s, millisecond,ms, microsecond,us
Also may fix some bugs that were reported.
Note, to convert fps to time evil_C needs to be used to get the scene.
- currently only distances work.
- user preferences, edit section to set the units and scale.
- option to display pairs (nicer for imperial display?)
- support for evaluating multiple comma separated values eg: 2',11" ..or.. 5ft, 4mil
- comma separated expressions/values accumulate 1+1,2**3,4cm/3
- attempted fast conversion from a value to a string so button drawing isn't too slow.
