Blender Git Loki

As requested; the Ramp shaders have same blending operators as were added
for texture blending.

Also made the popups for this blending stuff in more logical order.

- added python23.zip & zlib.pyd (bundled python modules for Win32)
provided by IanWill (thanks!)

- updated build systems to suit

Scripts:
- Campbell Barton updated his sel_same.py script;
- Added to Mesh scripts a call to Window.EditMode(0) to leave editmode before changing meshes.

BPython:
- small doc fixes / updates;
- added a call to undo_push_mesh inside Window.EditMode(0).

Mesh scripts could change the mesh but not the editmesh -- that would then overwrite the changed mesh. Made all mesh scripts leave edit mode before changing a mesh.

- small fix for the scons 'wininst' target, plus a typo correction :)

added a nice alert box when blender is run on a mac with less than 8Mb VRAM

Added crease value in NKey menu editmode

- recommitting the installer bmp file (with the -kb option this time)

- update for the win installer scripts ( added new scripts, etc ).

Oops, include file belonging to previous commit...

Plus: moved particle interaction and effect buttons back to a single
Object context. The proposed solution (sub context) has workflow issues,
(adds another click (no hotkey) to view settings)
whilst almost all Object buttons nicely fit in single view still.

This was on todo since first particle commit, actually the idea was to
move particle related issues to a special sub-context, but leave the
effects themselves in the Object main menu. Splitting off Particles from
the Effect system isn't in the scope of what is feasible now.

Also note; the current panel 'particle interaction' actually should be
a generic 'forces and collision' panel, since it's also relevant for
soft body feature (WIP)... that can be changed later.

Added new selection outline as option in View->View Properties panel. And
while working there added 3d cursor there as well.
I admit it isn't the best location ever, but let's do the threaded
discussions after 2.34 is out. :)

Removed unnecessary window-close on subsequent renders. This not only causes
delays and lotsof redraw events for the desktop, it also made it impossible
to drag a renderwindow to a desired position.
Now it only re-opens on render size changes. Maybe enables to have the
window permanent on 2nd monitor for extended desktops?

Note; the 'pref position' preset in F10 still works, but only on window
open of course.

Both transparent render and Unified render now behave with old speed
again. Use raytraced material, or set the "full Osa" option if you
like slow rendering, but with nice specular/shading/texture AA.

fix for #1479

Caused by commit Kester 7 weeks ago, adding sound actuator always crashes
when no sounds have been loaded. He forgot to put a MEM_Free within the
brackets. :)

Added framework OpenGL to link path, to enable the video memory check
in osx ghost now.

forgot to copy back a change from my config.opt to SConstruct

fixed a typo in Mathutil.Matrix (inverse --> invert)

Interface drawing tweaks:

* Made the shaded ends of popup menus the right shape,
when the button is aligned, connected to another button.
Found by desoto, fix by desoto

* Made the icons inside icon buttons scale up with zoom,
rather than just sit down in the bottom-left corner. The
scaling up is rather ugly - consider this a temporary
measure until we can find a nicer solution, on the
backburner for 2.35. Found once again by Bugmaster
Desoto, fix by ton.

Uncommited dashed lines to indicated 1x1 zoom. While it did look nice and useful, it caused some rather nasty slowdown on some 3D cards. It was decided to push the feature as well as further discussions on it (zooming indicator in corner or others means of showing zoom level) for after 2.34.

Added option to set 'full Osa' on non raytraced scenes. This makes sure
old files still use the old fast OSA, and when you want a specific
material to have specular/shader/texture AA you can set this individual.

When rendering ray_mir or ray_transp or ray_shadow the new OSA will be
effective by default however.

Still todo; make this switch work for transparant faces and unified...

new window behaviour for macos X computers :

if video card is open GL accelerated and has 16 Mo or more
start window in maximized mode wich is a full screen mode
but keeping access to other windows and sytem menu items

older comps start as usual
