Initially problem was caused by updated version of mingw-runtime which
changed behavior of snprintf and vsnprintf so %lf isn't anymore valid
for doubles.
According to manpages, %f is a correct format for snprintf for doubles.
* replace by BLI_snprintf in various places, note _snprintf on windows
does not properly null terminate the string.
* fix overflow in sequencer proxy code due to buffer being smaller than
specified size.
* fix some usage of snprintf as strcpy, this is will go wrong if the
string contains % characters.
* remove BLI_dynstr_printf function in gpu module, use BLI_dynstr_appendf
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
[#25159] Vertex locations dont read correctly and are not labeled correctly in the properties bar.
- non rna buttons can now have units set.
- calls with invalid units system now raises an assert().
- include .mxf in filter.
- ortho grid now draws scaled by the view3d 'Scale' setting, venomgfx noticed this was missing.
- so as not to confuse add scale next to unit display text, so rather then "Metres" it shows "Metres x 1.5" otherwise its confusing that grid lines are not in exact units.
- changed grid spacing to grid scale (needed for more logical behavior with units)
- when units are enabled grey out subdivisions.
- rna buttons with units set now use the units base value for snapping.
- bone head/tail radius could be set negative.
matt: removed a check in ui_is_but_unit() which made angle buttons return false, what was this for?
from Lorenzo Tozzi (oni_niubbo) with minor edits.
--- from the tracker
The present situation is this: due to bug#22274, during editing, UTF chars are stripped from buttons with a unit associated
(length, angles, etc.).
Example: if the button displays '90°' and you click on it with LMB, the editing string will become '90'.
The problem arises if you use microns: '34µm' becomes '34' that blender interprets as 34 meters. So clicking on a button
and hitting enter won't confirm the previous value, but will change it (very badly also).
Of course nobody is using microns in blender, but the problem will arise when we will implement areas and option 'Separate
Units' will be enabled. The value '2m² 3cm²' will become '2m' during editing.
This patch solves the problem rewriting the string in a smarter way than just stripping the UTF chars: the unit is translated
from unit->name_short ('µm') to unit->name_alt ('um'). So clicking on '34µm' the editing string will become
'34um'.

note: rather then allowing empty strings in name_alt field I made it so if the unit system was the default one a NULL name_alt will just strip the string, since its the default its not needed.
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.
