Centred dimension text that doesn't fit between the extension lines now
slides outside (text-outside placement), unless DIMTIX forces it to stay
inside. DIMTOFL is already satisfied for linear/aligned dims (their dim
line is always drawn between the extension points).
The remaining style flags are documented in place:
- DIMATFIT arrow-outside modes and DIMUPT need an arrow autofit pass.
- DIMTXTDIRECTION (RTL) needs single-line text direction support.
- DIMARCSYM / DIMJOGANG apply only to arc-length / jogged-radius dims,
which aren't shipped as entity variants.
- DIMUNIT is obsolete (superseded by DIMLUNIT).
