This feature takes a 'snapshot' of the visible+selected F-Curves, and displays these in the background as 'ghosts curves' in the background. Such curves are drawn semi-transparent, slightly darker, and with dotted lines.
To use, simply click the 'curve' button beside the Auto-Snapping selector. To clear, simply click that button again (with a different icon now).
These 'ghost curves' are stored per Graph Editor instance, and are not saved to file (i.e. per session only). They are useful to be used as guides when refining the shape of existing curves.
Now it is possible to add more keyframes to the 'active' F-Curve by simply Ctrl-LMB clicking in the graph space.
NOTE: more advanced polling callbacks are needed in the Graph Editor...
* Fix sometimes non-working close/open button.
* Fix panels being a bit out of the view on startup.
* Fix too large totrct region for view2d.
* Fix wrong panel order when changing vertical <-> horizontal.
* Fix wrong panel positions after switching contexts.
* Fix an access of freed memory when collapsing panels.
* Free align mode works again.
* Animations work again.
- use select as a suffix eg UV_OT_loop_select -> UV_OT_select_loop
- Each select all operator was using slightly different wording...
select_all, deselect_all, de_select_all, select_de_select_all -> select_all_toggle
- selection -> select
- POSE_OT_select_connected -> POSE_OT_select_linked to match other operators
- NODE_OT_delete_selection -> NODE_OT_delete since its not used in other operators
- ANIM_OT_previewrange_define -> ANIM_OT_previewrange_set to match other operators
- NODE_OT_fit_all -> NODE_OT_view_all to match other operators
- View2D_OT_* -> VIEW2D_OT_* to match VIEW3D
- View2D_OT_view_downscroll -> VIEW2D_OT_scroll_down more logical
- removed MARKER_OT_mouseselect_extend and made extend a boolean property of MARKER_OT_mouseselect
- MARKER_OT_mouseselect -> MARKER_OT_select
- GROUP_OT_group_remove -> GROUP_OT_objects_remove more logical since its removing objects from groups
- MESH_OT_removedoublesflag -> MESH_OT_remove_doubles
- redundant words MESH_OT_split_mesh -> MESH_OT_split, OBJECT_OT_object_delete -> OBJECT_OT_delete
renamed selection operator properties
extend_select -> extend
column_select -> column
select_children_only -> children_only
... Since these are all in the context of selection operators there is no need for the extra 'select' in the property name.

This setting means that instead of blindly replacing the existing values, the generator modifier will instead apply its effects on top of any existing modifiers (and/or curve data).
Thus, it is now possible to apply effects such sin/cos-based oscillations on top of keyframed motion.
* Envelope modifier now works correctly. Previously, the mapping was being done in the wrong order.
* Extra controls for modifiers now only draw when the F-Curve is the active one, so the view will be less cluttered in other cases.
Got the basic envelope modifier code working, including primitive drawing of relevant helper info in the graph view. It doesn't work in a very intuitive way yet, so I will recode it soon.
* Added GUI and fixed bugs in the Cycles Modifier. This replaces the old Cyclic Extrapolation settings, giving more fine-grained control over the results. You can now specify whether the keyframes are repeated before and/or after the range independently, also, the maximum number of cycles on either side can be controlled.
* TODO: it would be nice to have the last value held for cyclic+offset.
* Deleting modifiers now works
* Finished code for Expanded Polynomial and Factorised Polynomial UI's.
* Started UI code for 'Builtin Function' mode. There are still 4 controls to add there to use something other than simple mapping
* Finished/fixed up verification code for these so that values get initialised ok.
* Currently, this only works for the 'Expanded polynomial' mode, but this will be expanded to include the other modes too. Now you can modify the values and interactively see the graph in the view change.
* Disabled the backdrops (modifier 'panels') temporarily, as ROUNDBOX UI elements currently swallow all events, which is not good.
Note: the code here still uses the old-style UI definition code since the new stuff is still under heavy construction.
* Rewrote the Generator modifier to be more efficient and support more options
* A few UI tweaks for this, but the UI for this is still not yet functional though.
- Completed cleaning up the drawing code so that F-Curves with modifiers now get drawn to reflect this.
- Added a temporary operator to add modifiers (hotkey Ctrl-Shift-M)
As was discussed by the team the other day, copying keyframes (to copy/paste buffer) in DopeSheet/Graph Editor no longer relies on the selection status of the F-Curves, but rather on the selected keyframes only. This should be less confusing...
However, pasting keyframes still relies on having F-Curves selected to aid in the channel-matching process. There is still a lot of room for improvement in this area though (as noted in the code!).
This operator can be activated using the 'Alt-C' hotkey for now, and operates on selected + editable F-Curves. This is currently still highly experimental, and does crash
I've implemented this as a way to test out the FPoints/samples code, which will be used to provide better support of the dense F-Curves which result from importing Mocap/BVH data. These should use considerably less memory + have a few additional benefits over keyframes when they're working in a stable fashion.
* Added basic panels (Info, Drivers - where applicable, Modifiers) for editing active F-Curve/driver in Graph Editor. The buttons layouts here are really really rough, and have only got a few buttons to be sufficient for debugging purposes. Unfortunately, I don't have time to tweak these nicely now.
* Fixed indention errors with Action Groups used in Material actions
* Changing mode in the Graph Editor now recalculates colours
Useful goodies: most buttons for Image window back.
Not every button works! But what you can do:
- press Nkey to show/hide options
- use curves, with realtime updating
- image properties panel, load, browsing layers,
setting types
- paint panel
- plus new paint color picker panel! (why it wasn't
there in 2.4x is probably obvious, but now it can!)
Hrm... radial control should be added here too, and a nice
paint size cursor?
Currently, this is just used to print the 'name' of the active F-Curve in a panel for verification purposes. This is the recommended way of getting this info.
Graph Editor: added region for buttons (properties), so we can
check drivers again! Works like view3d, press NKEY. No buttons
there yet though... no time anymore today, it'll require some
RNA magic probably.
Made sliders behave correct in SpaceGraph and SpaceAction.
- no slider draw when all is visible
- sliders update correct when visibility changes.
Still an issue here to tackle; view2d->tot is used incorrect...
it's set on window size now (??), it should be the boundbox of
the entire contents. That allows correct slider draws and ops
like 'view home'.
Will poke Joshua tomorrow. :)
Graph editor: added refresh tagging on initialize; this is called
on browsing space types, as well on read files or switch screens.
(Makes the fancy fluorescent rainbow colors in channels appear!)
Now F-Curve channels in channels region are drawn with the same colour as their respective curve is drawn in the curves area. I've had to make a compromise to store such colour info in F-Curves themselves, which is not terribly ideal if the F-Curve gets reused in some way. However, for now, this will do (special tweaks can be made to make this work better though).
I've also added a colour-determination mode per curve which should in future allow more control over this. By default, all curves still use the old 'rainbow' style. The available types area:
* Old Rainbow - Colour is determined 'automatically' using a magic method which uses curve position + total curves to generate a colour.
* Auto RGB - Color is determined using the 'array index' stored in F-Curve for data-access. An unresolved issue with this is that all the curves with this will end up with exactly the same colour, leading to confusion (i.e. all location.x and scale.x properties could potentially all be the same red colour).
* Custom colour - self explanatory
Currently, there's a minor bug when loading old files where the colours don't get initialised yet. For now, just clicking in the Graph Editor after file-load will solve any of these problems.
Ton: it looks like area->refresh() isn't getting called after file read.
* Scene and World AnimDatas are now included in animation editors
* Keyframes for integer-value settings now get the FCURVE_INT_VALUES flag set for their F-Curves, which restricts those curves to only having integer-values. F-Curve displays have been altered accordingly, but some editing tools may still need tweaks to work with this.
* Fixed notifiers for Insert Keyframe -> Active Keying Set.
To use KeyingSets, simply Outliner-select items in the Datablocks view and press K to add to the active KeyingSet. Then keyframes can be inserted by choosing the 'Active Keying Set' option when inserting keyframes.
Important notes on the current implementation:
* Only properties directly inside some ID-block that is close to the root (i.e. main -> objects -> "someobj" -> location, or main -> materials -> "somemat" -> colour) can be accessed for now, as I haven't got the code for building the inner-parts of the paths working yet. Help on getting this working is welcome (hint to Brecht).
* Properties that can be safely included include simple properties "object -> Dupli Verts", entire arrays "object -> Location" or individual array elements "object -> Location -> y"
---
Also added typo fix for KeyingSet freeing. It was freeing the KeyingSet instead of it's paths.
* Uneditable F-Curves are drawn with dotted lines (and no handles)
* Muted F-Curves are drawn with a greyish colour. I'm not sure how visible this will be under some other colour schemes. Perhaps this needs as separate theme colour?
When fully implemented, these will be the clearest demonstration of 'Everything is Animateable', as they will allow users to define an arbitary group of settings through selecting items in the Datablocks (RNA-Viewer) View of the Outliner to define custom 'sets'. Such Keying Sets are known as the 'absolute' ones, which are created for a custom purpose.
Of course, 'builtin' Keying Sets will still be provided. Such built-in ones will not work on any particular paths, but will use context info to maintain the legacy method of inserting keyframes (via IKEY menu).
Currently, KeyingSets cannot be created/edited through the UI, though the backend code is in place to do this.
F-Curves can now be hidden/shown in the Graph Editor in one of 3 ways:
* Specialised VKEY toggle hotkey, which alters the visibility of all selected F-Curves
* The setting toggle operators (Shift-W, Alt-W, Ctrl-Shift-W)
* Checkmark (*1) boxes in front of names of F-Curves
This allows irrelevant curves to be hidden from the keyframes area only if you want them hidden. By default, all curves are visible. Also note that a separate hotkey is used now for toggling visibility (VKEY) instead of lumping it under select-all (AKEY) as in the past, which was a major cause of confusion.
Notes:
1) I've used the ICON_BLANK011 and ICON_BLANK012 icons, which in the current icon set are two states for a checkbox type thing. These defines should probably get renamed sometime, but I'll leave that up to Matt.
* Deleting keyframes should be safer now
* Graph Editor no longer crashes on F-Curves with no keyframes/samples
* Silenced console prints that occurred when an F-Curve had now keyframes.
* Group channels are drawn with better indention now
* Colors for group channels in Graph Editor are now initialised properly
* When selecting individual keyframes in Graph Editor, it is now possible to see which curve it belonged to, as the 'active' and 'selected' flags are set on that curve only.
When inserting keyframes on previous un-animated Objects/bones, F-Curves will be added into Action Groups into either "Object Transform" or <PoseChannel Name>. Ob->Material settings are not grouped for now to illustrate what's possible.
Old files are currently not patched to use do this, as it's still not clear whether this will be ideal.
* Removed Sequencer's own 'border zoom' tool. There is a generic one in View2D that should be used instead.
* Changed the hotkey for View2D's version of borderzoom to Shift-B
* Fixed a few hotkey mentions entries in old menus
* Added set start/end frame operators for TimeLine. (SKEY and EKEY)
* Fixed various issues in Graph Editor
- channels area is now drawn wide enough to show the 'protect' toggles without needing to scroll
- new Graph Editors have 'auto-snap' enabled by default
As creator of the Ipo I also reserve to right to kick it out
definitely :) To honour the wonderful contributions from Joshua
here it is; renamed space_ipo to space_graph!
Note; make, cmake and scons should work, msvc will require some
work now!
