Fixed a bug where the projection axis for the initial solution was wrong,
causing the solution to collapse into one point.
Made packing denser (by reducing the padding between face groups).

Implementation Least Squares Conformal Maps parameterization, based on
chapter 2 of:
Bruno Levy, Sylvain Petitjean, Nicolas Ray, Jerome Maillot. Least Squares
Conformal Maps for Automatic Texture Atlas Generation. In Siggraph 2002,
July 2002.
Seams: Stored as a flag (ME_SEAM) in the new MEdge struct, these seams define
where a mesh will be cut when executing LSCM unwrapping. Seams can be marked
and cleared in Edit Mode. Ctrl+EKEY will pop up a menu allowing to Clear or Mark
the selected edges as seams.
Select Linked in Face Select Mode now only selects linked faces if no seams
separate them. So if seams are defined, this will now select the 'face group'
defined by the seams. Hotkey is still LKEY.
LSCM Unwrap: unwrap UV's by calculating a conformal mapping (preserving local
angles). Based on seams, the selected faces will be 'cut'. If multiple
'face groups' are selected, they will be unwrapped separately and packed in
the image rectangle in the UV Editor. Packing uses a simple and fast
algorithm, only designed to avoid having overlapping faces.
LSCM can be found in the Unwrap menu (UKEY), and the UV Calculation panel.
Pinning: UV's can be pinned in the UV Editor. When LSCM Unwrap is then
executed, these UV's will stay in place, allowing to tweak the solution.
PKEY and ALT+PKEY will respectively pin and unpin selected UV's.
Face Select Mode Drawing Changes:
- Draw Seams option to enable disable drawing of seams
- Draw Faces option to enable drawing of selected faces in transparent purple
- Draw Hidden Edges option to enable drawing of edges of hidden faces
- Draw Edges option to enable drawing of edges of visible faces
The colors for these seams, faces and edges are themeable.
messages and pupmenu()s. Edited spelling and grammar,
stylistic consistency, etc.
I added the guidelines and rationale that I used to the
CMS here:
http://www.blender3d.org/cms/Language_and_terminology.338.0.html
Next step is to get icons in there, to make it easier to see
at a glance what sort of message (and how much attention
should be paid to it, or if it can be dismissed with a flick
of the mouse, eg. boring remove doubles notifications)

might be only an edge was missing in one of the loops.
Fix a crash that would sometimes happen when clicking the texture painting
button in the image window header. Made headerbuttons_packdummy a static
variable again. The uiDefBut call for the texture painting button stores a
reference to it, so it must be kept in memory.
new Properties panel (was first called Transform Properties). They include the
same settings as were previously found in the window header: Anim toggle,
Start/End frame, Speed, Tiles toggle, X repeat and Y repeat.
The Tiles button used to work incorrectly in 2.25, this is now fixed too.
The drawing of the UV Vertex transform buttons in the Properties panel used to
give popup error messages when in Edit Mode (uv_tface_editing_is_allowed is not
silent). Also these buttons would still draw in Edit Mode. Both are problems
are solved now.
it for the UV Image window (as Nkey replacement). Blendix can take
this further now.
Other little improvement: vertices in UV window now draw unselected
first, and then selected over it. Less confusing!
Next spaces: Action and Nla.
multiple functions and partially recoded. Because now all the uv mapping
settings are accessible throught the panel, no popus will be shown when
pressing 'U' to unwrap faces in face select mode. Also From Window to Cylinder
and From Window to Shpere became obsolete, as you can set this in the new
panel.
The panel contains buttons for all the existing uv mapping modes, and the
following settings:
- Cube size: For Cubical unwrapping.
- Radius: Radius for Cylindrical unwrapping.
- View Aligns Face, View Aligns Top, Align to Object: For Cylinder and Shpere.
Respectively means you are in front of the Cylinder/Sphere, look through the
Cylinder, or use the object rotation to determine how the cylinder is
positioned (old Cylindrical unwrapping).
- Polar XZ, Polar XY: With 'View Aligns Top' enabled, defines at which polar
you are looking.
- No Edges, Draw Edges, All Edges: Draw no edges, draw edges z-buffered on top,
draw all edges, without depth test.
All credits for this part (and also at least half of the other UV editor
improvements) go to Jens Ole Wund aka "bjornmose".

Constrained Scaling / Grabbing in the UV editor. Press XKEY or YKEY to scale
or move only in X or Y direction. XKEY and YKEY previously did mirroring while
scaling. Now mirroring can be done using the MKEY.
Grab, Rotate, Scale, Weld / Align and Mirror were added to a new Transform
sub-menu of the UVs menu.
- Draw Faces in the UV editor
- Draw Faces, selected in the UV editor, in the 3D view
- Draw Shadow Mesh in the UV editor (for faces unselected in the 3D view)
- Select Linked UVs (LKEY)
- Unlink Selection (Alt+LKEY)
- Stick (Local) UVs to Mesh Vertex on selection
- Active Face Select
- Reload Image
- Show / Hide Faces in the UV editor (H, Shift+H, Alt+H)
- Proportional Editing (O, Shift+O)
- Stitch, Limit Stitch UVs (snap by mesh vertex)
- Weld / Align UVs (WKEY)
- UVs Snap to Pixels on/off switch
- RMB in Texture Paint or Vertex Paint mode picks color
- Select Inverse in Faceselect mode
I hope these are all the features that were commited. The new UV Mapping
panel (and code) will follow later.
(MVert,MFace,etc) off into DNA_meshdata_types.h, to isolate areas
of source that actually edit mesh *data* vs. areas that just edit
mesh object information.
- while Faceselect mode on Subsurf, it didnt render the changes. this was
because the displaylist wasnt updated (the 3d window shows original mesh)
- added proper redraw event for F10-sound buttons when you add a new sound.
somehow sound doesnt play anymore here... have to check further.
colors. This because of the pretty weird (ab)use of load & make editmesh...
For each added undo step, the load_editmesh was fed with an empty mesh
to assign data to, without knowledge of what was in the original mesh.
That way UV and color data got lost.
Solved it in 2 steps:
1. removing the ->tface pointer from EditVlak, and make TFace a builtin
struct inside EditVlak. This didnt cost much extra mem, since it already
stored UV and color. This enabled some pretty cleanup in editmesh.c as
well, storing tface pointers was cumbersome.
2. for each undo step, it then generates always a tface and mcol block to
link to the undo Mesh.
Even when it wasn't in the actual Mesh, at exit editmode the original
Mesh is used as reference anyway, and undo-meshes are freed correctly.
The enormous commit is because I had to change the BLI_editVert.h file, and
found it was included in about every file unnecessary. I removed it there.
ALso found out that subsurf has code ready (unfinished) to make UV coords for
the displaylist in EditMode as well, nice to know for later...
include only (use BIF_interface.h instead)
- split up interface.c in two files: NEW: interface_panel.c
- removed the temporal text files
WARN: FIX AUTOMAKE AND MSVC!
