More testing with new system:

- Added markers (partially) back, ed_markers.c (temporary in spacetime,
where to put general stuff like this?), and added ED_markers.h for api.

- Mkey in timewindow shows marker (no icon, doesnt work yet).
(Adding operators gets easy :)

- Noted some conflict for operator storage... with markers being used all
over, added it to the screen level.

- More todos: view2d is stored in space, for time, etc. With regions we
could move this over, but better todo as post 2.5 project. Multiple 2d
views in area would be cool though.

Link pole controls to the parent of the bone with the IK constraint.

Presumably, this should give better result, but tests where not conclusive.

RNA
* Disable editable pointers for now, difficult to support well.
* Swap parameters in RNA_access.h functions to make it more
consistent.
* Rename rna members for operators to wmOperatorType.srna, and
wmOperator.ptr, to make the distincton a bit clearer.
�?� Removed the RNA_int_default and similar functions, they're too
confusing. RNA_property_is_set can still be used to achieve
the same goal.
* Add functions to create RNA pointers.

Some example code for RNA data access and operator properties:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNAExampleCode

* make sure this compiles with msvc too.
- note: there is no round() in msvc math.h, so I used floor(val+0.5)

patch #8583: Add support for gcc on irix

to compile blender with gcc on IRIX, IRIX_USE_GCC needs to be set to true in
user-def.mk.

Other changes related to irix:
* compile solid from extern/
* don't build plugins (yet) with "make release" when using gcc (the shell
script used assumes MIPSpro is installed)
* use statvfs instead of statfs on irix, like done on solaris
* use external libs from $(LCGDIR) instead of /usr/freeware
* use glew header files from $(LCGDIR)/glew instead of the ones installed on
the system (this applies to other platforms as well)
* ffmpeg support currently is disabled on irix

RNA
* Wrap most user editable data in DNA_mesh_types.h and DNA_meshdata_types.h.
Still needs to be improved in some areas though, especially how to deal
with data layers (expose per element or as array, or both?), and data in
face corners (bmesh type data structures are more logical here).

Tweaks to RNA defining to make some cases easier:
* Added range callback function for int/float.
* Added 'skip' callback for listbase and array iterators to skip items in
the collection.
* Extra error print when calling wrong define_property_*_sdna functions.
* Also made button code respect non_editable flag, is quick change though,
need to add support for properly graying out etc.

File had to be deleted in Brecht's RNA commit for Operator storage.

Work on gesture, some more cleaning.

- Added standard "tweak" gesture operator, which can be set per region, to
generate EVT_TWEAK events. You can configure tweaks for any mouse button
and have handlers for such events check for modifiers etc.
It even stores tweak direction (8 directions). Might be fun to experiment
with tweak gestures N, S, etc. :)
In general it can be used to replace the current tweak code in 2.48
(std_rmouse_transform).

Test added: on screen level it now adds LMB tweaks, if tweak-South it splits
the area. Will be removed of course.

- Added to Border operator a property to store event used to end border with.

- Moved the "AZone" triangle drawing to the right context (area). It was on
screen level, not respecting area-redraws. Also cleaned up drawing for it,
and moved the "swap buffers indicator" square to look nicer. Those squares
are only for test!

- event-match function had bad code for checking for event-value. Made a
"KM_ANY" define so keymaps can be defined ignoring event values.

- Gesture todo: lasso, "real gesture" (like blender now has)

backface culling wasnt working as it should in perspective view with the "Normal" option enabled.

painting onto faces was broken when the UV's or faces were flipped, reversing the order that LSCM and many other tools give.

* changed "Normal" falloff to only fade out at more extreme normals
* tooltip was wrong

* brush and airbrush match The Gimp, where the total color applied to a pixel during a stroke is limited by the brush opacity. With the airbrush option enabled it will accumulation over the opacity level (as it did before, irrespective of the settings).
* float buffer support for all painting operation and undo.
* only run brush_sample_tex() for textures brushes.
* redraw the brush outline even when nothing is painted.

== MSVC 2.50 projectfiles ==
- fixed dependencies and some glitches for RNA
- still WIP, but Blender Release and Blender Debug should compile now.

Only paint in the view clipped area when view clip is enabled (space defined by Alt+B).

[#18021] Rotating gets locked to axis after trackball rotate mode is entered

Reset transform restriction flags when switching to other transformations while running.

Also don't draw constraint if no constraint flag is on (old annoyance).

Fix bug with name templating text buttons (wrong event).

Cache the armature template graph while in editmode.
Display the number of joints in the selected template in the sketch panel
When using selected bones as template, turn off Connected if bone has a parent that is not copied.

maximum polyline between clipped rectangle and triangle was 6, but in some cases 7 points were set. set the maximum size of the polyline at 8 to be safe.

fix for painting onto faces from a side view in perspective mode, they would have jaggie clipping applied that looked bad.

The reason for this was with transforming screenspace points outside the face into UV space and when the bucket bounds was enough outside the face.
For faces viewed side on, this transformation would be applied incorrectly (a bit like trying to apply a projection matrix to a point behind the view), the buckets UV space coords would be incorrect and the wrong pixels would be initialized for that face.

solution is to clip the screenspace face with the bucket before getting the UVs. This should also be a bit faster since the clipped polyline will have a smaller bounding box.

RNA

* Added RNA for operators. This still uses ID properties internally,
but through the RNA API now. The OP_get/set_* API that was used is
replaced by the RNA API. Currently RNA properties for operators are
defined at runtime since it means operator registration can be done
in a single function.
* Changed the existing operators to use this system, I haven't defined
user interface names yet though. I also think there need to be some
conventions on which properties to expose to make these operators
usable in macros, for example if mouse coordinates should be stored
or not.
* When using ID properties through defined RNA properties, it now
checks that the ID property actually matches the RNA property and
removes/overwrites it otherwise. This ensures that you can safely
get/set arrays for example without having to worry that some
external thing may have changed the length.
* Documentation now has some information on RNA + ID properties.
