Fix T80819: Border zoom is isn't accurate in perspective view

Improved user experience by using viewport focal length
to calculate the new camera distance.

Also resizing the border to the same aspect ratio as
the window will help not zooming in more than expected.

BLI_rect: add resize_x/y functions

Without this, it's inconvenient to resize a single axis
and doesn't read very well.

Modifier: apply modifier now works for lattice

Cycles API: encapsulate Node socket members

This encapsulates Node socket members behind a set of specific methods;
as such it is no longer possible to directly access Node class members
from exporters and parts of Cycles.

The methods are defined via the NODE_SOCKET_API macros in `graph/
node.h`, and are for getting or setting a specific socket's value, as
well as querying or modifying the state of its update flag.

The setters will check whether the value has changed and tag the socket
as modified appropriately. This will let us know how a Node has changed
and what to update, which is the first concrete step toward a more
granular scene update system.

Since the setters will tag the Node sockets as modified when passed
different data, this patch also removes the various `modified` methods
on Nodes in favor of `Node::is_modified` which checks the sockets'
update flags status.

Sculpt/Paint: Add Paint Studio Light preset

This studio light preset is designed for color painting tasks. As color
are multiplied on top of the current studio light/matcap, this should be
as white as possible and with very soft speculars to avoid color
distorsion while showing the volume of the mesh.

Usual lack of protection against buffer overflows when manipulating

UI: Datatransfer modifier: set mix factor inactive when not in use

For Customdata layer copying, interpolation with the mixfactor is only
done for certain mix modes, now set the UI inactive if the mixfactor is
not in use.

Namely, the modes are the "Above / Below Threshold" which are only used
for flags, colors and normals and mixing is not supported in these cases.

Spotted while looking into T81914.

Fix: Animation, Draw active keyframe handles only when B�zier

Draw the handles for the active keyframe only when the interpolation type
is set to B�zier. This now matches the behaviour of handles of regular
(non-active) keyframes.

Fix T81890: Active keyframe changes on deselect of keyframe

Activate an FCurve only on selecting, and not on deselecting a keyframe
or a handle.

Fix T69911: Adaptive subdivision offscreen dicing does not work correctly if the camera is shifted

Code was assuming frustrum planes are symmetrical which is not the case
for shifting. This lead to a shrinking region if shift was negative (and
a growing region if shift was positive)

So instead of only keeping track of plane on one side (and mirroring
over in code) get the actual planes after shifting and use these
instead.

This code corrects this for ortho and perspective cameras, it does not
touch panoramic cameras.
