* Fixed padding for Graph Editor visibility toggles
* Reverted many of the tweaks to Timeline UI for now (for the reasons outlined in earlier mail)
* NLA Editor now (mostly) uses the new channel-drawing API
* Made NLA Editing functions more aware of transitions.
- A transition can only be added between a pair of action-clips. Previous, two transitions could be added next to each other, which has undefined behaviour
- Deleting a strip with transition(s) on either side will remove the transitions too. Feedback welcome on this
- The 'type' setting for NLA-Strips is no longer editable. This was dangerous as it could result in transitions with undefined behaviour (though nothing would happen).
* Menus for adding F-Modifiers now only show relevant modifiers (i.e. 'Invalid' is not included in the list, and 'Cycles' doesn't need to be shown for NLA since we've got repeat)
* Function Generator and Noise F-Modifiers now have complete GUI's. A few settings were missed during the porting process.
* F-Modifier buttons now have their source-ID's included in the RNA Pointers used. This didn't get them animateable directly, but is a step closer.
* Most of the F-Modifiers have been ported to use the layout engine + RNA for drawing their buttons now. This plays much nicer with various button-layouts.
--> As a nice demo, try adding a Noise Modifier to a NLA-strip, and change the 'size' setting to about 2 to see some effects.
* Generator and Envelope modifiers haven't been ported yet since they're quite complex (requiring more time + energy), and as such, have been made to have some temporary error prints instead. Will check on this tomorrow.
* Finished/cleaned up the RNA-wrapping of most FModifiers.
TODO's (help requested... Brecht?):
Generator modifier's UI cannot be wrapped yet using the layout engine (though I might try using the old system only), as I'm having some trouble wrapping the coefficients array for this (see rna_fcurve.c - rna_def_fmodifier_generator())
* Using the Ctrl-Shift-M hotkey, F-Modifiers can be added to all the selected strips.
* F-Modifiers can also be added/tweaked from the NLA N-Key properties. The UI now uses the same code as for the graph editor ones.
The UI drawing here is currently messed up from the NLA side, since it seems combining normal layout stuff and old-style uiBlocks doesn't seem to work too well (BUT! the buttons are at least functional).
Next up, I'll need to recode the buttons panel for the Graph Editor so that all of the drawing can be migrated over to use the new layout engine.
* F-Modifier UI drawing/handling is now defined in a separate file so that it will be more suitable for inclusion into the NLA Editor's buttons.
* Started removing F-Curve dependence from the modifier drawing code, which wasn't strictly necessary
* Fixed F-Curve RNA wrapping to correctly use FPoints instead of the bulkier BPoints. Although nobody was likely to have encountered bugs here yet, this would almost certainly have contributed to some segfaults/data corruption along the track.
Started cleaning up FModifiers in preparation for allowing them to be used on NLA Strips.
This commit separates the 'Built-in Function' mode for the Generator modifier out into its own modifier, since it was being quite frequently used (and the RNA wrapping for this used to be quite hackish).
BACKWARDS COMPATABILITY WARNING:
Old files with FModifiers saved (i.e. old 2.5 files, but not any others) will not load correctly as a result of these changes (the wrong modifiers will be shown). I've decided that there are not likely to be many files affected by this yet, but doing this will result in a much nicer modifiers-define list in the long run.
For now, some of these polls may be a bit too restrictive, but at least we have some unified+cleaned bases to work from now (instead of relying on the generic ED_operator_area_active).
As with the DopeSheet, the names of operators in the Graph Editor have been cleaned up, and operators have been added to menus as appropriate to show their availability.
Tweaked a few DopeSheet operator names to be more in line with the Graph Editor equivalents, and vica versa.
TODO: now, the operator poll callbacks here need checking...
For fun, added 'sinc' (i.e. y = sin(pi*x)/(pi*x)) as a type of builtin function usable through the generator modifier. This makes a nice 'jolt' which tapers off.
* Fix buttons jumping around when resizing and zoom. Part of this was
adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels. V2D_LOCKOFS_X/Y is
now taken into account in more places in the view2d code, to avoid
zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).
* View3D/Graph/Image editors now use the same PanelType system as the
buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.
* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
object instead.
* Fix autotexspace -> auto_texspace in py script.
* Added back backgrounds behind buttons for modifiers and driver targets
* 'Protect' toggle doesn't draw for F-Curves with no keyframes to prevent editing on anymore
* Inserting keyframes on objects using builtin keyingsets now use the right names
* Added extra parameter to generic unique name finding function BLI_uniquename() for specifying the delimeter between non-unique parts of the name and digits.
* Driver target variables now get unique names by default.
* The UI for adding and modifying drivers is now functional, and reflects the new way they work. It has also been tidied up a bit (from the previous incarnation), with RNA buttons starting to be used (currently limited to the 'Path' settings).
* Fixed errors in RNA wrapping for drivers
Drivers now support multiple targets which act as 'variables'. The targets have a short 'name' (see later), and reference some property (in much the same way as F-Curves do, using RNA-Paths) which acts as the 'value'.
These named variables can then be used in a Python Expression which relates them to each other for more fine-grained control over the result of the driver. By using only the names of these variables in the expressions, we are able to define expressions/relationships in a much more readable way, as data access is separated from data use. This makes the underlying relationships easier to understand.
By default, if no Python Expression is given, the variables are simply averaged together, so old files won't break. :)
For example, check the following diagram (thanks Cessen/Nathan V from Peach team):

TODO List:
* Depsgraph building for new driver relationships doesn't work yet. This needs to be recoded again, but this new system makes this much easier, since the targets are clearly defined (i.e. no need to parse py expressions to get list of objects)
* Graph Editor interface for editing these needs to be rewritten
* Python function for evaluating these expressions is needed (Campbell?)
More cleanup!
- removed old UI font completely, including from uiBeginBlock
- emboss hints for uiBlock only have three types now;
Regular, Pulldown, or "Nothing" (only icon/text)
- removed old font path from Userdef
- removed all old button theme hinting
- removed old "auto block" to merge buttons in groups
(was only in use for radiosity buttons)
And went over all warnings. One hooray for make giving clean output :)
Well, we need uniform definitions for warnings, so people at least fix
them... here's the real bad bugs I found:
- in mesh code, a call to editmesh mixed *em and *me
- in armature, ED_util.h was not included, so no warnings for wrong call
to ED_undo_push()
- The extern Py api .h was not included in the bpy_interface.c, showing
a several calls using different args.
Further just added the missing includes, and removed unused vars.
This new modifier clamps the values of the F-Curve to lie within specified bounds, much like Limit Location/Rotation/Scale constraints do. You can limit by time range(s) and/or value range(s).
* Invalid drivers are now tagged accordingly and are not evaluated until they are manually refreshed using the 'Update Dependencies' button
* Drivers with errors have a error warning shown in their UI
* Rearranged the UI buttons a bit for drivers, adding support for a 'remove' driver button.
* 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.
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.
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)
* 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
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.
