Allow selecting how the new location/rotation/scale is combined with
the existing transformation. This is most useful for rotation, which
has multiple options, and scale, which previously could only replace.
Allow combining location, rotation and scale at the same time,
using one constraint. The mixing modes are based on matrix
multiplication, but handle scale in a way that avoids creating
shear.

Upon close inspection, the way the Offset mode works in the
Copy Rotation constraint makes no sense, and in fact, destroys
the rotation of its owner unless either it's single axis, or
the order is set specifically to `ZYX Euler`.
Since it can't simply be changed because of backward compatibility
concerns, replace the checkbox with a dropdown that provides a set
of new modes that actually make sense.
Specifically, add a mode that simply adds Euler components together,
and two options that use matrix multiplication in different order.
The Python use_offset property is replaced with compatibility stubs.

`transform conversions.c` is a file that is getting too big (almost 10,000 lines).
So it's a good idea to split it into smaller files.

Instead use vertical cursor motion for Y axis shear.
This removes the shear_axis option completely since we now have two
axis options used by shear it's not needed.
Now all wire edges linked to the merged vertex are used for split faces.

Since pependicular snap depends on `snapTarget` it is important to indicate where this target is so as not to confuse users.
So draw a pivot where the target is and a dotted line toward the perpendicular snap point.

Option for snapping to the nearest point of a reference coordinate.
The patch also adds Edge Center and Perpendicular snaps to the ruler.
