Note only particles/dupliobjects existing in the current frame will be taken into account.

Dev note: the 'object' part of the code becomes really ugly, it will need a serious
refactor (probably using some kind of wrapper around Object/Bone/PoseBone/DupliObject),
nobody (not even me) will be able to follow this code soon.

devide chars by 255, not 256...

Export actually works perfectly well, here (Unity probably just does not supports scale in tex mapping...).
But importer completely ignored texmap data when working with non-nodal materials - we at least can support
offset and scale data here!

That was not really true, since each strip from NLA would be exported as an animstack already.

Supporting 'all actions' feature was in fact a bit hairy, because actions are not
linked to objects in Blender (you can assign any action to any object). Did it this way:

for all exported objects:
    for all actions in bpy.data.actions:
        if action is 100% compatible with object:
            temp assign this action to the object, and bake animation of this object only into an animstack

This does not make great code, but seems to work rather well... Just be sure to not have invalid
paths in your actions! ;)

Rough guess, 2.0 for obj (because of quite heavy changes in it this fall/winter),
and 3.0 for FBX (assuming 1.0 = 6.1 exporter, and 2.0 = 7.x importer, makes 3.0 = 7.4 exporter)

FBX export: do not apply Armature modifiers when we export armature objects, rather than use animation or not!

FBX export: always copy org (blenddata) matrices (when not done implicitely by e.g. multiplication).

Looks like nothing is expected for BindPose nodes here? Anyway, I'd guess those are
doublons with cluster data... :/

Yet another stupid mistake. :/

Normals are not optional for STL so remove the option from the UI.

Clamp branchL to min 0.0 (negative branch length does not make much sense, and
non-int power of negative numbers gives complex numbers...).

This kind of target app compatibility feature is not well suited to an export addon,
would better be in a dedicated pre-export tool.

Was broken since apply modifiers and other geom types support was added.

If new option "Simplify Skinning" is set (by default), only four most significant weights are kept.
Else, only a warning is issued.

Also added more OrederedDict's!

* When exporting actions from NLA, do not export global 'scene' action (unless there is no actions in NLA!).
* Export actions from NLA as all starting from 0.
* Fix take time to be one frame longer than the longest animstack exported.

Should fix Unity timeline weirdness (as long as you use standard framerates like 25fps, 30fps, 29.97fps, etc.).

FBX: Add support to export other geometries (curves, metaballs, etc.) as meshes, and implement the 'apply modifiers' option.

(in addition to global anim from scene).

Even if they do not affect the same properties, multi-layers interactions are rather complex.

Note: tested on unity & houdini with some basic mesh/rig, needs some more serious testing with real animated characters!
