Bugfix for depsgraph error leading to lagging, caused by local
constraint ipo drivers and proxies.

1) Revert previous commit, rendering negative won't work that simple...
Needs much more attention.
2) Fix for zcombine node:
- it skipped execution when no image rgba out was used
- didnt work for FSA yet

Allows negative light to result in negative diffuse and 'combined'
when you have world exposure set. (it used to clip it in 0-1, now it
mirrors the values)

stupid me! if you move var declarations sometimes you have to add
assignments outside of the var declarations!

in my tiredness I didn't declare some vars at the top of the block.

Added another 2 checks for if an image has the premul flag set, 1 in the image
compositor node, another in render_realtime_texture. Note that multilayer images
in the image compositor node do not respect the premul flag (though I did write
commented out code for it).

As far as I can tell, the premul option never worked for multilayer images in the
image node, so I'm a little nervous about making it work properly there.

ton, any comments?

Reverted the change of auto-turning on premul for images from last
commit. I still think this is a good idea, but needs more discussion.

Basically, the way the premul option worked before is it actually
changed the image data to be premul (for each pixel it multipled r,g,b by a) when
loading an image. So if a user wanted his image to be key, yet
still work in the renderer (which expects premul) he'd be stuck.
Also, it was kindof confusing how if you painted something in the image,
then saved it with premul on, when next you loaded the image it'd have
changed (especially since the image editor painting seems to paint in
key, not premul).

Object drawing was setting switching glDepthMask(GL_FALSE); even when no particles were drawn.
Added an annoying message when people press the F key to say FaceSel mode was removed.

The "premul" option for images had a very bad implementation. It
basically flagged the image so that on next load/reload, the image
data would be converted to premul. This was very confusing to the
user, as it meant premul wouldn't take effect will the image was
reloaded, and it would also change the image data, which the user
might've been painting.

To fix this, I've removed this behaviour and instead made the premul
option apply at render time. During render while evaluating an image
texture, if the image has the premul flag set then the premul operation
is done on the texture result data, thus not touching the image data
at all.

Also, I've made premul be turned on by default.

Bugfix #8283: PyConstraints menu problems

The menu listing the scripts available for use was not working correctly for newly created PyConstraints. This was caused by a missing initialisation for the 'active' index.

make the file and image selector convert relative paths.

== Shift-G - Select Grouped menu in PoseMode ==

In PoseMode, the Shift-G menu now presents options for selecting bones in the same layer or the same bone-group.

== Custom Bone Colours - Per Group Colour-Sets ==

Now it is possible to define a custom colour set per bone group. This allows rigs to look consistent across different computers with different themes. As such, the bone-groups buttons have been reshuffled to present the settings in a better way.

Colour sets are now selected from a menu with descriptive names, instead of using a slider. Choose the 'Custom Set' entry to use a custom set of colours for the active group. The sets of theme colours have been retained, and can be used directly, or as the basis for a new custom colour set (when any one of the colour controls is touched).

For bone-groups that haven't had any custom colour set used yet, a default 'test' set is used. This uses bright versions of the RGB colours.

Particles' angular velocity mode "velocity" was actually just a duplicate of "spin" without any angular velocity, so it was removed.

== BPython API ==

Fixing mistake in Blender_ShowHelp() function: argument to Blender_Run() should be passed directly as a string, not encapsulated in a tuple (aka "s", not "(s)").

It seems my fix for bug 8274 broke hair, so reverting that and opening the bug again in the tracker :)

Fix for bug: [#8274] Particle System cannot be persuaded to recalculate
-The exact time for a particle being unborn or alive needed some adjusting

Fix for bug #8206: crash with 0 particle hairs and softbody for the
particle system.

- Fix for bug #8264: SSS turned off by "default" render settings button,
I also added a button to control enabling/disabling SSS for render.
- Fix for potential halo sorting crash.
- Add a newline at the end of a file to remove gcc warning.

Added a global string to be used for the tempdir. since the user preference is not loaded in background mode and the user preference is not validated and has no fallback.
'btempdir' is set with BLI_where_is_temp() - This tries to use U.tempdir but falls back to $TEMP or /tmp/
