- material editor: each texture channel can be individually switched,
instead of the old 'septex' which only showed the active one

- rendering: the 'stencil' option now works to stencil out normals as well

(special requests from our manual master, s68)

- fixed bug: 'header select' themecolor had no alpha, causing antialiased
lines not drawn (triangles in buttons for example)
- correct colors for channels in texture buttons
- fixed bug: using proportional editing, the extra wire draw had incorrect
matrix
- fixed bug: drawing in imagewindow didnt work anymore... was a very old
one! the wrong pointer was read, and it accidentally went OK, until now
- selecting vertices with multiple 3d wins open works again

More fixes in object drawing:

- transparent faces in editmode don't write in zbuffer anymore (prevents
drawing errors) but still read (so behind the subsurf faces for example)
- improved drawing 'handles' for subsurf editing
- going in editmode to Solid view, will draw extra wire always, including
transparent faces when set
- works in all combos... http://www.blender.org/docs/ton/subsurf.html

- fixed error; padplus/padminus didnt work in buttonswindow anymore
- improved buttonswin: when dragging window edge, the buttons dont
rescale, but stay same size

Added mirror function to the code and to the Wkey menu (at the end)

Added PADENTER confirmation to transform.

- Added PADENTER to knife confirm, to make it more consistant
with okee() et. al.

- Preserved selections in undo.

- Fixed spurious "recalc norm" enties in Undo.

Numerical input in transformation modes (Grab, Rotate, Scale,
Warp, Shear, Shrink/Fatten). It works with the transformations mode,
it doesn't replace them, so just enter grab, scale or rotate mode
as usual and start typing. Both numpad and non-numpad works for the
numbers.

Tab switches between axis (the axis that is being modified has
parenthesis)
Backspace clears the current axis. Twice clears all axis.
Minus (-) switches between positive and negative value.

The mouse is now disabled when you type (as soon as you use one of
the numerical keys). You can use Nkey to switch between numerical
and mouse driven mode.

The minus key on the numpad still affects the PET in mouse-driven
mode, but affects the sign of the number in numerical input.

Fixes Makefile for intern/SoundSystem/intern.

- fixed error; the vertices didnt draw anymore in editmode with sold draw.
was caused because i only tested the new cool 'draw wire extra'. :)

- by default, in solid draw mode & editmode, it does a 'draw wire extra'
now, giving nice clean editmesh drawing.

- there's still a few quirks, i do a test now... this commit is to have
a good working blender in cvs. the whole drawing system is such chaos...

A few bugfixes to the vgrouping methods

Axis constraint in transform for grab mode
Axis constraint in size mode

note: the original behavior when constraining with middle mouse in object mode is weird. I've leave it that way, but I think it would be a good time to fix it. Another thing: in object mode, you can only constrain size to local axis. Global axis would involve either screwing the matrix (which stinks) or modifying the vert coords directly (which is a no no)

Please also note that this breaks the mirroring combo.
I'll be commiting my edit mode mirror function soon to fix that.

Coder note:

You can now call the transform function with an additional parameter to constraint to an axis.
example:

transform('g'*'X')
transform('s'*'y')
transform('r'*'z')

Capital axis letter for global axis, lower case for local axis

fixed warnings and errors in buttons_object.c

Mesh drawing stuff!

- in zbuffer mode, vertices will be blended 50% in... and when you increase
vertex size larger than 2 pixels, it will draw them smaller
- removed all 'wire extra' calls (there were dozens!) and replaced it with
simple call where it belongs.
This drawing mode is becoming nice & stable... maybe something to make
default on for new objects? Makes selecting quite easier...

- Subsurf: in editmode, with new 'Optimal' option set, the mesh itself
will not draw, but instead it draws 'handles' to the vertices. Looks
extremely clean!

- matched drawing of default grid-floor (persp) to ortho grid

- killed drawing vertices outside of main drawing loop, apart from the
routine that uses mouse-selecting. (tekenvertices_ext()). It was an old
optimize routine which became quite useless.

Helpline drawing in transform (semi broken in this commit)
This is only usefull for rotate now, but the axis constraining code has a part that depended on this, so I commit this part first.

For coders:

void constline(float *center, float *dir, int col)
Draw an infinite line on the screen. col is the color argument. It must be cpack compatible

void project_short_infiniteline(float *vec, float *dir, short *adr1, short *adr2);
clips infinite line to screen border

For coders:

Axis CONST and variable rename in transform in preparation of further commits
Parsing code to supply axis constraint with the mode (Broken knows what I'm talking about)

Constraint stuff from tuhopuu including (but probably not limited too):

Axis options for TrackTo
LockTrack
FollowPath

Auto creation of TrackTo constraint from Ctrl-T (old track still an option)

Auto creation of FollowPath when parenting to path (Normal parent still an option)

Backward compatibility stuff to convert the per object axis settings to per constraint when a Track constraint is present.

Function to convert old track to constraint (commented out)

Revamped the constraints interface with Matt's work from tuhopuu and the stuff we were discussing earlier.

--------------------
For coders:

unique_constraint_name and *new_constraint_data moved to the kernel (constraint.c)

new Projf function in arithb gives the projection of a vector on another vector

add_new_constraint now takes a constraint type (int) parameter

add_constraint_to_object(bConstraint *con, Object *ob) to link a constraint to an object

add_constraint_to_client(bConstraint *con) to link constraint to current client (object or bone)

add_influence_key_to_constraint (bConstraint *con) to (eventually) add a keyframe to the influence IPO of a constraint

fixed bugs:

- faceselect mode works again
- selecting vertices for lattices, surfaces and curves works again
- in previewrender sometimes a square was drawn, which was texture-crop

- forgot to set 'minimal theme' callback for sliders, causing a crash when
displaying Constraint Panel in F7 menu.

- another formula for 'draw wire extra'. this time it doen't scale, but
only moves z-values in drawing in zbuffer. still matrix art I don't
fully grasp... but it seems to work!
