Changed selection flag used for the selected_nodes context property from SELECT to NODE_SELECT. These are just incidentally the same, but NODE_SELECT should be used for nodes.
In addition don't store unfinished links in the nodetree->links list any more. This makes code a bit safer because all links in that list can be considered valid now. The temporary bNodeLinkDrag structs used by the modal linking operator are now also stored in a list in SpaceNode, so these links can be drawn too (this separation also allows different display of temporary links, e.g. currently they are drawn on top of all nodes).
One node update call (for nodes within group nodetrees) was using the
wrong nodetree (node-editor's nodetree, not the group) which meant
that the wrong RNA context for such nodes would get used, resulting in
errors when trying to keyframe such nodes.
Hopefully this is the last time I have to fix these bugs...
most local modifier,GPU,ImBuf and Interface functions are now static.
also fixed an error were the fluid modifier definition and the header didnt have the same number of args.
The backdrop zoom factor for new node-editor instances was not set
(i.e. was default initialised to 0). Now, this gets set to 1.0.
Also, set the property default in RNA to match this.
When using masks or other simple 3D elements in composites, doing
a layer re-rendering on a node is a bit clumsy all the time.
This commit does two things to help:
- new hotkey "Z" in node editor automatically finds render layer
that changed and re-renders it + composites
- option "Auto Render" does same, but then after every transform
edit in 3D window
The latter is experimental; real & proper system for this requires
full threaded render support (like previews). But it works!
Demo file:

Important fix:
After any render, all the render layers were tagged "changed", which
caused any edit to first totally recomposte everthing. Now it only
composites changes.
Implementation notes
- DAG scene flush now sets 'changed' flags in render layer nodes
- Added notifier for 'transform finished' to trigger the update,
this is temporarily.
* Added Backdrop Panel inside the "Properties" area.
* Hard limit for the "zoom" value. Negative values doesn't make sense.
* Added a missing notifier for the Node backdrop move operator.
Compositor operators now have better poll check, so they won't
show up in operator search or hotkeys for other node views.
- backimage move, size
- read renderlayers
+ changed lines connecting nodes:
they now use a linewidth of 1.5px for the light foreground and 4px for the dark background.
this should fix node-lines not being visible on almost black or all white backdrops.
+ muted nodes now also show a red tinted header if they are hidden (collapsed)
+ both active and selected nodes show a (now properly antialiased) highlighting frame
+ fixed a small error in dropshadow code resulting in a gap at borders
+ fixed a tiny error for the collapsing indicators (triangles) - they were not symmetrical.
Ton will add proper theme colors for the node-editor in the coming days.
- New Node editor now opens with larger view, the default
was like zoomed in factor 2.
- Add node via menu now shows new node more visible
- Click on (material) node now doesn't re-render the entire
tree anymore, much nicer.
- Duplicate node creates preview image immediate
Compositor: "Read & Compo Full Sample Buffers" option stopped after
1 pass; the break callback was returning '1' falsely.
Also made it show "wait cursor" again, since it doesn't run in
thread nor updates UI while compositing buffers. Check console for
progress for now.
Node editor
Some nodes - when muted - didn't draw a red line to indicate
a pass-on action. Stil, the node then is muted and either passes
on a buffer of same type, or just black.
To more clearly indicate muting, it now draws the header in a
reddish blended color too.
