`SETVAR DIMSCALE 24` was stored in the header but never reached new
dimensions: they were created with no overrides, and the header DIMSCALE
was only a fallback for styles whose scale is zero.
As in AutoCAD, the header DIM* variables that differ from the current
dimension style are now its overrides, and new dimensions take them on
(`Drawing::dim_overrides`). Existing dimensions keep their size. Making a
style current, or editing the current style, sets the variables back to
the style's values (`Drawing::sync_dim_vars`), so
`dimstyle {"name": "Standard", "DIMSCALE": 24}` still works.
GETVAR/SETVAR read DIM* variables the header doesn't carry from the
current style.
Dimension extents now use the same scale as the geometry (the style with
the dimension's overrides) instead of multiplying by the header DIMSCALE.
A DIMSCALE of zero (AutoCAD: scale to the layout viewport) falls back to
the drawing's DIMSCALE and then 1 instead of 1e-9.
Reading DXF, $DIMDSEP becomes the separator character, as the DIMSTYLE
table already is, so AutoCAD's header variables don't turn into spurious
overrides.
