Reported by Sean Kennedy. The Fill Opacity setting on Export was missing a tooltip.

Made some tweaks to transformation matrix of <svg> node to make
it so origin from Inkscape matches Blender origin.

Currently only affects files from Inkscape, for others it's not
so much clear what origin should be.

Based on the patch from aldero (juanC), thanks!

AnimAll: Update location description and open by default, now that we have tabs in toolbar there's no need to make space

The Edit Linked Library panel now only appears in the Relations tab

the script was checking for selected strips one by one,
and sometimes this drives into freeze (can't explain why, but its obviously
a bad way to do it...

now it uses context.selected_editable_sequences, now it is more efficient
and the bug seems to be solved.

This adds the "Navigation" category for the addon, thus assigning it a tab. Due to this, I've also made the panel open by default. It was closed.

This adds the 3D Printing category to the addon such that it's placed in a "3D Printing" tab of the 3D View Toolbar.

AnimAll: Adding info message for preventing people to add keyframes for Shape and Points at the same time. Will not disable it because maybe there's a valid use.

AnimAll: Enable keying of shapekeys on bezier curves (Thanks to Aligorith for yet another API fix!). Also one extra effort to make the use of shapekey animation clearer.

Add support for Surface objects
Add support for simple point animation in meshes and lattices
UI improvements for Shapekey animation

Caching of 'delete strokes' was incorrect, making it impossible to
change parameters after conversion of strokes.

Thanks to Alexander Nedovizin for coding first version of this function.

Internal faces are now correctly deleted and smooth shading is applied.

Fix: matrix operations
Based on report in anonymous forum.

Fix: GUI layout, aligned buttons

New functionality: GStretch converts grease pencil strokes to vertices.

First commit via git, please don't shoot me if I did something wrong.

this is an internal name only.

Improved: exportable hair amount

Hair exported only the view percentage, full amount gets exported now. allowing much higher counts than what could get displayed. also since the lowest count (0) is no longer divided by the view percentage it removes a "division by 0" error.

Comment for vertex color was repeated inside the vertex loop creating unnecessary comments.

[TextureAtlas Script] Classes renaming just not to get the same names as in different addons. Fix for ManualUnwrap hidden faces. Version 0.2.1

Add option to export texture references to the active images of each face.  This is useful to some users.

Re-added the Coordinate System and Up Axis options.  Apparently XNA uses a right handed system and the option was useful for some users.  Oops!
