- A dimension snaps to what it draws: the objects of its block (read from a
file), expanded like block references, or else the lines generated from it
(Endpoint on their ends, Midpoint, Intersection, Nearest); Node on its
definition points.
- TEXT justified other than left-baseline (as read from DXF, group 11)
snaps (Insertion) and grips at its alignment point; attributes too.
- The snap grid starts at SNAPBASE and turns by SNAPANG (drawing variables,
defaults 0,0 and 0 degrees). SETVAR takes `x,y` for point variables.
- Hatches are left out of object snaps unless OSNAPHATCH is 1 (new session
variable, default 0 as in AutoCAD).
