View2D - assorted wip changes (nothing to see here)

missed saving a small change

fix for [#18040] FBX writes incorrect relative paths.
http://projects.blender.org/tracker/index.php?func=detail&aid=18040&group_id=9&atid=125

Added Blender.sys.relpath(path, start='//')
similar to os.path.relpath but uses blendfile path rather then the current working directory.

Also use python exceptions rather then providing our own ones.

added a function to resolve case insensitive paths in BPySys and an option to use it in BPyImage
- Useful when loading files with saved in windows on a *nix system.

RNA: review of commits in the past days, check the diffs for the
many small changes, but the two bigger ones are:

* Sensors and controllers now use inheritance, rather than pointing
to the data in a separate struct. Had to add some new RNA define
functionality to support this better.
* DNA_meta_types.h was marked as done but still missing many things,
now completed.

Retarget bug: missing angle cost on last bone.

2.5

- after closing button (having used it), it sends empty mousemove for
invoking new modal handler on same button. Don't know better solution
for now, at least this way WM handles everything. :)

- experiment: moved button handlers to area level, that way it respects
handlers on higher hierarchical level, like moving area edges.
Als interesting is that you can have a button active (texteditor) and
use a similar button in other area.
This can also be done on region level even.

On todo: proper notifier events for redraw! Don't want all areas to draw
on simple refreshes

Made PyRNA props iterable, so you can do things like...

for ob in bpy.objects:
print(ob.name)

for i, lay in bpy.scenes["Scene"].layer:
print('%d %d' % i, lay)

Added RNA functions from PyRNA
* RNA_property_enum_value
* RNA_property_enum_identifier
To get an enum string from a value and a value from an enum.

BPy_StructRNA types (objects, meshes, images etc) can now be used as dictionary keys.

Lots of stuff; couldn't commit in parts because of refactor work.

* Changes in interface/ module

This commit brings back the way how buttons/menus work under control
of WM event system. The previous implementation extended usage of
handlers and operators in an interesting but confusing way. Better to
try it first according the design specs. :)

Most obviously:
- modal-handler operators are not stored anymore in regions/areas/windows.
such modal handlers own their operator, and should remove it themselves.
- removed code to move handlers from one queue to another.
(needs review with brecht!)
- WM fix: the API call to remove a modal handler got removed. This was a
dangerous thing anyway, and you should leave that to the event system.
Now, if a handler modal() call gets a cancel/finish return, it frees
itself in event system. WM_event_remove_modal_handler was a confusing
call anyway!

Todo:

- allow button-activate to refresh after using button
- re-enable arrow keys for menus
(do both after commit)

- review return values of operator callbacks in interface_ops.c

* Fixes in WM system

- Freeing areas/regions/windows, also on quit, now correctly closes
running modal handlers
- On starting a modal handler, the handler now stores previous area
and region context, so they send proper notifiers etc.

* Other fixes

- Area-split operator had bug, wrong minimal size checking. This
solves error when trying to split a very narrow area.
- removed DNA_USHORT_FIX from screen_types.h, gave warning
- operators didn't get ID name copied when activated, needed for
later re-use or saving.

RNA - Wrapped a few more simple Object transforms.

Note: Rotations are still exposed directly in radians. We should probably do some wrapping around this, perhaps at UI-level?

View2D - Some more tweaks...

* Improved scrollbar drawing a bit more - only cosmetic lines
* Added new view2d view-matrix api method to only use 'cur' coordinates on one axis, for use when drawing markers, etc. that need to be glued to a certain time but stay fixed in space in another dimension. This should improve the sitation for drawing markers
* To aid testing, adding markers now sets the marker to have frame number as it's "name". This will need to be removed later...

mingw was giving errors...
sourceblenderpythoninternbpy_rna.c:1018: error: initializer element is not constant
sourceblenderpythoninternbpy_rna.c:1018: error: (near initialization for `pyrna_prop_Type.tp_get

Assign get generic get/sets before PyType_Ready runs

* rna_property completed
CAUTION: some defines like PROP_INT in DNA_property_types.h are the same
as enums in RNA_types.h, and may be encounter hidden errors in future.

* after discussion with cambo on IRC, change the #ifndef's to #undefs instead:
Pre-Python 3.0 has strings default non-unicode, so checks and handling should be done so too.

* make sure there are no redefinitions (I'm using py2.5 and ie PyUnicode_Check define exists

The GL-based renderer was removed. Freestyle now uses Blender's internal renderer to raster strokes.

The render generated from Freestyle's data is currently stored in the original scene's render structure ( as 'freestyle_render'): when the render database is generated, the scene's geometrical data is first imported into Freestyle and strokes are calculated. The generated strokes are used to create a Blender scene, rendered independently. The render result is used in the rendering loop.

The final rendering is performed the same way edge rendering is, in a function ('freestyle_enhance_add') operating on each individual render part. Freestyle strokes are only included if the toggle button "Freestyle" (in the 'Output' panel) is active and if the "Freestyle" render layer is also selected. Freestyle's panel appears when the toggle button 'Freestyle' is active.

IMPORTANT: as of now, rendering ONLY works when OSA is disabled and when Xparts = Yparts = 1. If these settings are not set, a bogus image will be created.

To make the render happen, many modifications had to be made:
- the Canvas::Draw and Operators::create methods no longer render strokes. They only generate shading and locational information.
- a BlenderStrokeRenderer class was added to turn Freestyle's strokes into a Blender scene. Basically, the scene consists of strokes in their projected image 2D coordinates and an orthographic camera centered in the middle of the corresponding canvas. The scene is rendered using vertex colors, in shadeless mode (therefore, no lamp is needed). BlenderStrokeRenderer uses the old GLTextureManager to load textures (as required by the StrokeRenderer class), even though stroke textures are probably not supported (not tested). After the scene is rendered, it is safely and automatically discarded.
- AppCanvas' code was greatly reduced to the bare minimum. The former AppCanvas would use an OpenGL-based back buffer and z buffer to determine the scene's color and depth information. In the future, this data will be determined from the corresponding render passes. Currently, the integration is not achieved so all style modules using depth/color information are sure to fail.
- before, Freestyle needed an OpenGL context to determine the camera's information and to compute the view map. As of now, the modelview and projection matrices are fully determined using data provided by Blender. This means both perspective and orthographic projections are supported. The AppGLWidget will very soon be removed completely.

RNA
* DNA_packedFile_types: added rna definitions for packed files
* also experimentally filled in correct struct 'PackedFile' in image rna for testing.
* updated MSVC projectfiles (also for rna_curve.c and rna_vfont.c)

Note:
I removed PackedFile->flags, I did grep through source and a complete recompile of blender trunk svn without them too, so they obviously aren't needed anymore. A bit of cleaning up :)

RNA: Added missing *srna's to curve functions.
