00291b5cf4 [GameEngine] Commit all Kester's changes made to the gameengine to restore 2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them

That was about it.

There are a few things that needs double checking:

* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.

3ce1dc9065 Area lights and more...
- New lamp type added "Area". This uses the radiosity formula (Stoke) to
  calculate the amount of energy which is received from a plane. Result
  is very nice local light, which nicely spreads out.
- Area lamps have a 'gamma' option to control the light spread
- Area lamp builtin sizes: square, rect, cube & box. Only first 2 are
  implemented. Set a type, and define area size
- Button area size won't affect the amount of energy. But scaling the lamp
  in 3d window will do. This is to cover the case when you scale an entire
  scene, the light then will remain identical
  If you just want to change area lamp size, use buttons when you dont want
  to make the scene too bright or too dark
- Since area lights realistically are sensitive for distance (quadratic), the
  effect it has is quickly too much, or too less. For this the "Dist" value
  in Lamp can be used. Set it at Dist=10 to have reasonable light on distance
  10 Blender units (assumed you didnt scale lamp object).
- I tried square sized specularity, but this looked totally weird. Not
  committed
- Plan is to extend area light with 3d dimensions, boxes and cubes.
- Note that area light is one-sided, towards negative Z. I need to design
  a nice drawing method for it.

Area Shadow

- Since there are a lot of variables associated with soft shadow, they now
  only are available for Area lights. Allowing spot & normal lamp to have
  soft shadow is possible though, but will require a reorganisation of the
  Lamp buttons. Is a point of research & feedback still.
- Apart from area size, you now can individually set amount of samples in
  X and Y direction (for area lamp type 'Rect'). For box type area lamp,
  this will become 3 dimensions
- Area shadows have four options:
  "Clip circle" : only uses a circular shape of samples, gives smoother
  results
  "Dither" : use a 2x2 dither mask
  "Jitter" : applys a pseudo-random offset to samples
  "Umbra" : extra emphasis on area that's fully in shadow.

Raytrace speedup

- improved filling in faces in Octree. Large faces occupied too many nodes
- added a coherence check; rays fired sequentially that begin and end in
  same octree nodes, and that don't intersect, are quickly rejected
- rendering shadow scenes benefits from this 20-40%. My statue test monkey
  file now renders in 19 seconds (was 30).

Plus:

- adjusted specular max to 511, and made sure Blinn spec has again this
  incredible small spec size
- for UI rounded theme: the color "button" displayed RGB color too dark
- fixed countall() function, to also include Subsurf totals
- removed setting the 'near' clipping for pressing dot-key numpad
- when you press the buttons-window icon for 'Shading Context' the context
  automaticilly switches as with F5 hotkey

Please be warned that this is not a release... settings in files might not
work as it did, nor guaranteed to work when we do a release. :)

97d4dbc9c3 Another commit for raytracing, now with glass refraction & fresnel!
Changelog:

- enable refraction with button "Ray Transp" in Material buttons.
- set "Angular Index" value for amount of refraction.
- use the "Alpha" value to define transparency.
- remember to set a higher "Depth" too... glass can bounce quite some
  more than expected.
- for correct refraction, 3D models MUST have normals pointing in the
  right direction (consistently pointing outside).
- refraction 'sees' the thickness of glass based on what you model. So
  make for realistic glass both sides of a surface.

- I needed to do some rewriting for correct mirroring/refraction,
  especially to prevent specularity being blended away.
  Solved this with localizing shading results in the rendercore.c.
  Now specularity correctly is added, and reduces the 'mirror' value.
- Localizing more parts of the render code is being planned. The old
  render heavily relies on struct Render and struct Osa to store globals.
  For scanline render no problem, but recursive raytracing dislikes that.

- done test with gamma-corrected summation of colors during tracing, is
  commented out still. But this will give more balanced reflections. Now
  dark reflections that are reflected in a bright surface seem incorrect.

- Introduced 'Fresnel' effect for Mirror and Transparency. This
  influences the amount of mirror/transparency based at viewing angle.
  Next to a new Fresnel slider, also a 'falloff' button has been added to
  define the way it spreads.
- Fresnel also works for Ztransp rendering

- created new Panel for Raytrace options
  I have to evaluate still where it all should be logically located.
- material preview shows fake reflection and fake refraction as well.

a5247cf5b8 - fixed bug in wrong event code, causing some plugin buttons not working
- added redraw events to plugin buttons, to show updates better

4bec8ba7d5 Fixing loose ends:
- nkey menu for buttonswindow (hex values) couldnt be restored yet, is
  for next release
- replaced Nkey in IpoWindow with Panel, this now displays the buttons
  that were formerly in 'anim buttons' as well; to view the boundbox
  values of all visible curves, and adjust it.
- the new panel also has the 'set speed' option, fixed stuff in it and
  added better errorwarning... still not a very well coded tool!

4efdabfbbc 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

f420f87610 - added Theme for File Window
- made grid drawing using the main theme color
- was annoyed with the primitive grid... so coded something that allows
  zooming in and out a 100fold without losing gridlines
- brought back 'NKEY' for mesh editmode
- added to this a 'median' option; when more vertices selected you see
  the average coordinate. works nice when inputting values as well
  (todo: make this for other editmodes)
- renamed the 'NKEY' panel to 'Transform Properties', also fixed in
  pulldown menu.

I am off for the rest of the day. More committing fun tomorrow!

0321602b65 - The basic layer for Themes in place!
- currently only implemented for 3d window
- create as many themes you like, and name them
- default theme is not editable, and always will be defined at startup
  (initTheme)
- saves in .B.blend
- themes for spaces can become local too, so you can set individual
  3d windows at theme 'Maya' or so. (to be implemented)
- it uses alpha as well...!

API:
This doesnt use the old method with BFCOLORID blahblah. The API is copied
from OpenGL conventions (naming) as much as possible:

- void BIF_ThemeColor(ScrArea *sa, int colorid)
  sets a color... id's are in BIF_resources.h (TH_GRID, TH_WIRE, etc)

- void BIF_ThemeColorShade(ScrArea *sa, int colorid, int offset)
  sets a color with offset, no more weird COLORSHADE_LGREY stuff

- void BIF_GetThemeColor3fv(ScrArea *sa, int colorid, float *col)
  like opengl, this gives you in *col the three rgb values

- void BIF_GetThemeColor4ubv(ScrArea *sa, int colorid, char *col)
  or the one to get 4 bytes

ThemeColor calls for globals (UI etc) can also call NULL for *sa... this
is to be implemented still.

Next step: cleaning up interface.c for all weird colorcalls.

44344b3501 - More code for handling Panels in other windows.
Added the 'Nkey' object menu as Panel now. Live updates, whoohoo!

closing them, minimizing, etc will follow. first bring back vertex
selection :)

44b32134ae - converted constraint buttons, they're a Panel in Object main menu
- converted sound buttons, part of Scene
- special request Matt: headers of windows 2 pixels higher! (test)
- special request Stefano: icons instead of menu for buttons-header
- 'data browse' buttons now almost all in buttonswindow.
- almost all buttons have been panelized now.

next stage: cleaning up usage of color in Blender, to allow presests!

ceb26d2a4e - experiment: changed drawing style of Panels to minimal and fully
transparant.
- converted the Texture buttons, they're nice too!

12236bcdfa - restored scriptlink buttons
i tried to find place for it in the other menus, like material, object,
  camera, etc. But thats hard... now it's just one nice Panel, without
  the idiot headerbuttons icons!
- changed drawing of 'tabbed' Panels. The old method takes too much space.
  hint from xype! Dragging tabbed Panels can be done with the right hand
  circle. designers are welcom to tweak this.
  main reason: dragging is not meant to be happening a lot... pressing tabs
  is more important.

0d03929b9b Another huge commit!!!
First, check on the new files, which are listed below.
The new butspace.h is a local include, only to be used for the buttons
drawn in the buttonswindow.

- editbuts, animbuts, gamebuts, displaybuts, paintbuts,  work now
- i quite completely reorganized it, it's now nicely telling you what
  context it is in
- sorting error in panel align fixed (tabs were flipping)
- align works correctly automatic when you click around in Blender
- editsca.c renamed to buttons_logic.h
- button names are truncated from the right for allmost all buttons
  (except text buttons and number buttons)
- while dragging panels, you cannot move them outside window anymore

And of course fixed loads of little bugs I encountered while testing
it all. This is a version I really need good test & feedback for.

Next step: restoring material/lamp/texture/world
