* Measure Panel - Version 0.8.1 

* Some cleanup in the panels UI structure.
* Non-meshes do not show wrong data now (from previously selected meshes).
* Removed version history/changelog from the script. This is handled by svn/git anyway. 
* Added missing normal&volume comments.

It's very helpful to use one or two "Empty" objects with
"Snap during transform" enabled for fast measurement.
Version history:
v0.8.0 - Volume calculation
v0.7.15 - Measurement of face normals by TNae + extended to cover all cases.
Grouped measured values inside boxes.
v0.7.14
Fixed matrix calculation order.
Replaced region3d_get_2d_coordinates with location_3d_to_region_2d"
from bpy_extras.view3d_utils.
v0.7.13 - Moved property definitions to registration function.
Changed automatic callback adding to manual,
the current API doesn't seem to allow this top be automatically yet.
Various API fixes.
v0.7.12 - Moved setting of properties to callback function
(it is bad practise to set it in the draw code).
Fixed distance calculation of parented objects.
API change: add_modal_handler -> modal_handler_add
Regression: Had to disable area display for selection with
more than 2 meshes.
Fixed Local/Global vert-loc calculations in EditMode.
v0.7.11 - Applied patch by Filiciss Muhgue that fixes the text in quad view.
v0.7.10 - Applied patch by Filiciss Muhgue that (mostly) fixes the quad view.
Patch link: https://projects.blender.org/tracker/?func=
detail&atid=127&aid=24932&group_id=9
Thanks for that!
Removed (now) unneeded "attr" setting for properties.
v0.7.9 - Updated scene properties for changes in property API.
See http://lists.blender.org/pipermail/bf-committers/
2010-September/028654.html
Synced API changes in/from local copy.
v0.7.8 - Various Py API changes by Campbell ...
bl_default_closed -> bl_options = {'DEFAULT_CLOSED'}
x.verts -> x.vertices
@classmethod def poll(cls, context)
No "location" in bl_info->name
bl_info->api
v0.7.7 - One more change to the callback registration code.
Now it should finally work as intended.
v0.7.6 - API changes (r885, r886) - register & unregister function
v0.7.5.3 - Small fix for bug in v0.7.5.1
(location was off when object was moved)
v0.7.5.2 - Changed callback registration back to original code &
fixed bug in there (use bl_idname instead of bl_label)
v0.7.5.1 - Global mode is now taking rotation into account properly.
v0.7.5 - Fixed lagging and drawing issues.
v0.7.4 - Fixed the modal_handler_add and callback_add code.
Thanks to jesterKing for pointing that out :-)
v0.7.3.1 - Fixed bug that made all lines in Blender stippled :-)
v0.7.3 - Added display of delta x/y/z value in 3d view.
* Inspired by warpi's patch here:
http://blenderartists.org/forum/showpost.php?p=1671033&postcount=47
* Also added display of dx,dy,dz lines
* Changed the "dist" colors to something not already used
by x/y/z axes.
v0.7.2 - Merged changes from trunk (scripts_addons r847):
* obj.matrix -> obj.matrix_world
* vert.selected -> vert.select
* face.selected -> face.select
* bl_info: warning, wiki_url, tracker_url
* removed __bpydoc__
* Use fontid=0 for blf functions. 0 is the default font.
v0.7.1 - Merged changes by Campbell:
* Fix for API change: Collections like context.selected_objects
no longer return None for empty lists.
* Update for mathutils, also stripped some redundant
conversions (Mostly "Vector()" stuff)
v0.7 - Initial support for drawing lines.
(Thanks to Algorith for applying my perspective_matrix patch.)
The distance value (in BUs) is also drawn in the 3D view now.
Also fixed some wrong calculations of global/local distances.
Now it's really "what you see is what is calculated".
Use bl_info for Add-On information.
Use "3D View" in category & name
Renamed reenter_editmode to view3d.reenter_editmode.
Renamed panel_measure.py into space_view3d_panel_measure.py
Active object is only used for edit-mode now. Measurement
with exactly one sel. (but not necessarily active) object
now gets the obj via the sel-object array.
API change Mathutils -> mathutils (r557)
Deselecting 1 of 2 objects now works correctly (active object is ignored).
Force a redraw of the area so disabling the "measure_panel_draw"
checkbox will clear the line/text.
Only calculate area (CPU heavy) if a "area" checkbox is enabled.
v0.6.4 - Fixed unneeded meshdata duplication (sometimes crashes Blender).
The script now correctly calculated the surface area (faceAreaGlobal)
of scaled meshes.
http://projects.blender.org/tracker/
?func=detail&atid=453&aid=21913&group_id=153
v0.6.3 - Added register & unregister functions.
v0.6.2 - Fixed precision of second area property.
Reduced display precision to 5 (instead of 6).
Added (commented out code) for shortcut [F5] for
updating EditMode selection & calculation.
Changed the script so it can be managed from the "Add-Ons" tab
in the user preferences.
Corrected FSF address.
v0.6.1 - Updated reenter_editmode operator description.
Fixed search for selected mesh objects.
Added "BU^2" after values that are not yet translated via "unit".
v0.6
*) Fix: Removed EditMode/ObjectMode toggle stuff. This causes all the
crashes and is generally not stable.
Instead I've added a manual "refresh" button.
I registered a new operator OBJECT_OT_reenter_editmode for this.
*) Use "unit" settings (i.e. none/metric/imperial)
*) Fix: Only display surface area (>=3 objects) if return value is >=0.
*) Minor: Renamed objectFaceArea to objectSurfaceArea
*) Updated Vector() and tuple() usage.
*) Fixed some comments.
v0.5 - Global surface area (object mode) is now calculated as well.
Support area calculation for face selection.
Also made measurement panel closed by default. (Area calculation
may use up a lot of CPU/RAM in extreme cases)
v0.4.1 - Various cleanups.
Using the shorter "scene" instead of "context.scene"
New functions measureGlobal() and measureLocal() for
user-friendly access to the "space" setting.
v0.4 - Calculate & display the surface area of mesh
objects (local space only right now).
Expanded global/local switch.
Made "local" option for 3Dcursor-only in edit mode actually work.
Fixed local/global calculation for 3Dcursor<->vertex in edit mode.
v0.3.2 - Fixed calculation & display of local/global coordinates.
The user can now select via dropdown which space is wanted/needed
Basically this is a bugfix and new feature at the same time :-)
v0.3.1 - Fixed bug where "measure_panel_dist" wasn't defined
before it was used.
Also added the distance calculation "origin -> 3D cursor" for edit mode.
v0.3 - Support for mesh edit mode (1 or 2 selected vertices)
v0.2.1 - Small fix (selecting nothing didn't calculate the distance
of the cursor from the origin anymore)
v0.2 - Distance value is now displayed via a FloatProperty widget (and
therefore saved to file too right now [according to ideasman42].
The value is save inside the scene right now.)
Thanks goes to ideasman42 (Campbell Barton) for helping me out on this.
v0.1 - Initial revision. Seems to work fine for most purposes.
