Drawing Improvements:
* Single 'dots' now draw rounded
* Strokes being drawn are drawn 'solid' instead of as dotted lines
Eraser:
* Now operates interactively, so no more wait to see if stuff was erased
* An influence circle is now drawn - the radius of this is defined as the thickness^2
Improved accuracy of the eraser a bit. Now it does a boundbox test first before trying to erase strokes, which means that other (rather unrelated) strokes are less likely to be affected as well.
This commit introduces the ability to erase strokes. Admittedly, the code for this is not totally stable yet, and doesn't always produce optimum results. I'm committing now for backup purposes.
It currently uses the lasso code to check whether segments of the strokes (a segment occurs between two recorded points) occur inside a region defined by the 'eraser' stroke, or any intersections it makes with the 'eraser' stroke.
There are multiple ways to erase strokes:
* With 'Draw Mode' on, use RMB-drag to erase
* With a tablet, use the 'eraser' end of the stylus
* Hold the Alt Key, and use the 'selection' mouse-button (i.e. LMB if mouse-button swapping is on, RMB otherwise) to erase. For this one, this is necessary to avoid overriding the view-rotation hotkey combo for 2-button mice!
Todo:
* 3d-strokes are not correctly mapped back to screen-space for sampling yet
* Drawing of eraser strokes is still not distinctive enough
* After running a few times, may cause stack corruption/segfaults, so be careful!
== Bugfixes ==
* Grease-Pencil Onion-Skinning works again. Onionskining was being supplied the wrong frames, and the alpha factor was still the old one used for 0-255 ranged colour values
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
Press ALT+B in 3d window, draw a rect, and it becomes a clipping
volume of 4 planes. You then can rotate the view anyway you like.
Works for each 3d window individually.
Disable it with another ALT+B press.
Commit is huge because it had to change all selection code as well.
The user-clipping planes are in 'eye space', the other clipping
happens in projected 'viewport space'.
Nice to notice is that the 'x=3200' convention (to denote a coordinate
is clipped) now is a define. Define value is still a number though... but
we now can get up to screens of 12000 pixels without issues!
Known issue; here it refuses to draw the 'object centers' or Lamp icons
within the clipping region. Can't find any reason for it... however, we
might move to non-pixmaps for it anyway.
Testing might reveil numerous issues, will be standby for it.

submitted by Alexander, changes/improvements are:
- Moved to new Panel in Scene buttons "Post Effects". Together with other
postprocessing options, such as Edge render. It is also not called DoF,
this because that's a bit pretending too much then. It's a zblur still!
- Made it render Alpha as well
- Made it use and deliver float buffers
- Huge cleanup of zblur.c code, was very messy. It was alling things in render
code without need even (win matrices, transform faces, etc)
- Fixed errors in using Z values (zbuffer is signed int)
- Removed very weird gamma corrections for front/back half
- Tweaked gaussian table, allow variable 'Sigma' to be set for gauss curve
- Didn't copy 'auto focus' yet. Use of this is very limited, and gives
false expectations, nor works for rendering anims with deamons well.
Main issue remains: it's not a very advanced feature... I still doubt
very much if this deserves to be released. Spent 2 days on trying to get
the key issues solved, with not much results.
- gauss filter code has weird side effects on large blur size
- having unsharp (blurred) in front also blurs what's around in back.
only blurred in back with sharp in front works a little bit
- severe aliasing errors... also due the code splitting in 2 halves
- doesnt work with unified yet
- won't work for halos, spot halos or transparant faces
Anyhoo... It was promised to be committed, so now artists can play with it.
Who knows it's useful after all, or some fixes can be implemented. :)
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
