This commit implements basic clipboard support for movie tracking data
int clip editor. Used own implementation of clipboard like it's done
for sequencer.
Ideally it needed to be switched to more general clipboard system, but
currently this system is designed for text data only and it need to
be re-designed itself. But this feature is quite useful since object
tracking is implemented, so it should be OK to live with such own
implementation for a while.
Special notifiers used for scene deletion which lead to undo pushes
after SCENE_OT_delete operator happening with scene still present in
the mainfile. That was a reason why operator redo used to restore
scene.
It's not so obvious why special notifier type is needed for scene
set and deletion -- it confuses undo system without having some
obvious advantages. Using "direct" scene deletion and setting
seems to be working fine so let's see if there'll be some issues
with this.
This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs.
To use the functionality change the bump mapping method to "best quality"
Previous "best quality" setting becomes "medium quality" now.
For non OpenGL 3.0 GPUs this becomes the same as "medium quality"
Also:
* added tooltip descriptions to the bump method settings.
* modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL.
Bicubic shader by Morten Mikkelsen. Thanks a lot!
Oh...and FIRST!
Linking changes active object which is pretty useful in general,
but which totally confuses edit mode (i.e. it becoming not so obvious
to leave from edit mode and inwalid tools in toolbar might be displayed)
so disable link/append when in edit mode
bug was that uiPupMenuSaveOver(...) could run the WM API call function which freed the operator, within the low level invoke function which kept using the freed memory.
Changed uiPupMenuSaveOver(...) to only show a popup so the caller needs to check if the file exists and should be immediately written (which was done everywhere except for blend saving anyway).
* added note that operators invoke/exec funcs cant call WM_operator_call(...) on themselves, ends up using freed memory.
* added BLI_is_file(path), checks the file exists and isnt a directory.
changes
* undo now checks screen jobs only, was checking all jobs before so a material preview could make an undo fail.
now this is only limiteds for render/fluid bake/bake.
* the redo UI is now disabled when screen operators run.
Moved tweak threshold value to user preferences
This threshold might be needed to be tweaked when working with tables, i.e.
to prevent tap+slight movement be treated as tweak event.
If enter is pressed outside of any button in menu, generate two menu return values:
- UI_RETURN_CANCEL so button wouldn't be executed
- UI_RETURN_POPUP_OK so callback associated with popup block would be executed
