possible from python, but it's still work in progress.
Pointers and collections are restricted to types derived from
IDPropertyGroup (same as for operators), because RNA knows how to
allocate/deallocate those.
Collections have .add() and .remove(number) functions that can be
used. The remove function should be fixed to take an other argument
than a number.
With the IDPropertyGroup restriction, pointers are more like nested
structs. They don't have add(), remove() yet, not sure where to put
them. Currently the pointer / nested struct is automatically allocated
in the get() function, this needs to be fixed, rule is that RNA get()
will not change any data for thread safety.
Also, it is only possible to add properties to structs after they have
been registered, which needs to be improved as well.
Example code:
http://www.pasteall.org/7201/python
* Add RenderResult.load_from_file to load whole multilayer exr's at once.
* Removed x/y offset from RenderLayer.load_from_file, better to encourage
using offset in begin_result() to minimize memory usage.
* Added WITH_OPENEXR in some screen/file/image module for scons/make, exr
was not working in some places there.
- use RNA_struct_blender_type_set to set the type to NULL before its freed
There is a memory error here when reloading scripts - ui_handler_panel_region, need to look into theis further.
lay = result.layers[0]
lay.rect_from_file("somefile.png", part.x, part.y)
If the source image is bigger then the render layer x/y offsets can be used to choose the part of the image use.
An engine to use for output can now be selected an influences what
shows in the buttons window, only showing relevant data. The idea
behind this is to make it more clear what is supported where, make
the system more pluggable for external render/game engines, and save
space hiding stuff that is not relevant anyway.
* Top header now has an engine menu, to choose between the blender
render engine, game engine, and other future external engines.
* If the game engine is enabled, the buttons window should show
only properties that work in the game engine, and similarly for
the render engine.
* Moved panels from the logic space and game tabs to the physics,
scene and world tabs instead, and removed the game tab.
* Materials and textures tabs should eventually become game
specific too, to better show what is supported.
This adds a RenderEngine type to RNA, which can be subclassed
in python (c++ will follow once we support subclassing there).
It's very basic, but plugs into the pipeline nicely. Two example
scripts:

Issues:
* Render runs in a separate thread, and there is unrestricted
access, so it's possible to crash blender with unsafe access.
* Save buffers and full sample are not supported yet.
