- was displaying 1cm as 10mm because of double precission problem.
- typing in numbers without any units will use the units displayed before editing the value.
- fixed some errors

fix for errors evaluating user input when units are disabled

added time units, currently only used when metric or imperial are enabled.

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.

some uv/vcol collapse fixes. need to still work out the rules of collapsing regions of geometry that include seams, not sure how best to handle that.

fixed some problems in weld, collapse, and collapse uvs

*Instance support is only enabled if target mesh uses more than 4 faces
if theres very few faces its not worth it to create a separated tree for beinng reused.
should speedup some particle renders.

This "fixes" a bug relationed with a arithmetic precision on instances and raytrace of very close objects
which usually happens on rendering (almost) overlapping alpha-enabled leafs/feathers

- missing a decref for new pytypes
- remove needless strlen

user interface units, off by default.

- 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.

* imperial long/short *
- mile, mi
- yard, yd
- foot, '
- inch, "
- thou, mil

* metric long/short *
kilometer, km
meter, m
centimeter, cm
millimeter, mm
micrometer, um
nanometer, nm
picometer, pm

Fix ray_trace_shadow_tra

Added libsamplerate.a in Makefile

The structure for names where this lib is could need fix...
will need feedback from other make users.

Also Python lib in svn is wrong, intel lib???

2.5: User Preferences:

* Code cleanup. Note: This file doesn't follow the UI code guidelines due to some more complex layout structure.
Will think about this special case.

* Added new Sound Options into the System settings.

2.5

Makefiles to get new AUD stuff to compile (OSX 10.3 PPC)
It uses lib/samplerate, which gets committed soon too

SVN maintenance.

fix instance support when using SIMD

svn merge -r 22364:22371 https://svn.blender.org/svnroot/bf-blender/branches/blender2.5/blender

Fix for batch mode.

Smoke: fix problem with more than 1 domain + collision and flow groups - reported by nudelZ aka "Master of Smoke"

Animation Editors: Code Cleanup Part 1 - Drawing

Finally started refactoring the drawing code for animation editors so that all the drawing (of the channels/names list) is done using standardised code for all the editors.

A little specialised system for this has been made, and is now used for DopeSheet and Graph Editor drawing. This should make it easier to add new channel types with less effort.

Protect/mute toggles are now always clamped to the right-hand edge of the channels list. So you can now make the list wider to view longer names fully. However, since the mouse-handling hasn't been fixed yet, this won't always work.

TODOs:
* make mouse-click handling code use this system too, simplifying things to 1-2 lines of code there. Maybe this could be made to use UI widgets instead at a later date?
* NLA still needs to be ported to this system

fix for using subtype units that are not defined as a part of types. eg.
prop= RNA_def_property(srna, "cursor_location", PROP_FLOAT, PROP_XYZ|PROP_UNIT_LENGTH);
