Disable transform and mask display when there's no active clip.
It's not a matter of returning fallback dimensions if there's no
slip, it's also matter of making it so stabilization and distortion
routines are aware of clip == NULL which is really crappy.
Also almost all the operators are disabled in clip editor without
active clip already anyway.
Also tweaked header UI a bit to not display mask stuff when there's
no active clip,
Allow duplicating splines from inactive layers. This way it's
more useful IMO than restricting duplication to an active layer.
TODO: What should be a behavior for clipboard (currently it copies
splines from an active layer only)?
when in ortho mode, zoom would dolly rather then zooming which
doesn't make much sense, now check ortho and zoom in that case
(nice behavior for locked quad view).
- swap Z/Y axis so Z changes hue and X/Y change location.
this way you can use ndof like a joystick and Z rotation like a dial
for the hue.
- change sensitivity when shift is held to be 1/5th
This is really a workaround which brings back direct display
list creation from drawing code. This is rather nasty to do
but proper solution would require some major sequencer redesign.
Use Z axis for the edge direction for edges and vertex pairs.
Issue raised in T38592, now edge select and vert-pairs share logic
for calculating orientation and the active vertex determines direction.
The "Cast Shadows" worked as expected, but it can cause problem in some cases.
For example, when using strand render, we need disabling only buffer shadows,
but the previous changes made that impossible. "Cast Shadows" should be added
as a newly created option.
This allows us to make materials that don't cast ray shadows.
Turning off this property can reduce the rendering time slightly.
Note: RNA path is changed to "use_cast_shadows" as well. The older
path "use_cast_buffer_shadows" still can be used as its alias, but
it will be removed after updating some addons.
