C3D-0142 · Wider letter spacing + R/W dims onto ROAD-RW-TEXT [ROAD-LABELS-3] done

Redraws the curved Camellia Cir label with letter spacing widened from 0.62 to 0.95 times text height, since a curve crowds glyphs on the inside of the arc, and moves the IPF-to-centreline R/W dimensions onto ROAD-RW-TEXT. Records that SdskCurvedText cannot be created from a ticket: no managed wrapper and no registered .NET command produces one.

C# payload

// Road labels: wider letter spacing on the curve, and the R/W dimensions moved to ROAD-RW-TEXT.
//
// TEXT-ALONG-CURVE - SETTLED, do not re-litigate: the proper entity is SdskCurvedText (DXF
// SDSK_CURVEDTEXT, app SDSK). It IS registered in this session but has NO managed .NET wrapper in
// any loaded assembly, and NO registered .NET command creates one (scanned every CommandMethod in
// every loaded assembly: only Map's MAPTEXT2ANN/MAPMTEXT2ANN/MAPLABEL2ANN matched, which convert
// existing text to annotation). Express Tools ARCTEXT/AcDbArcAlignedText is not registered here
// either. So a ticket CANNOT create curved text natively - one MText per character is the method.
//
// Letter spacing widened from 0.62*H to 0.95*H: on a curve the glyphs crowd together on the inside
// of the arc, so nominal advance is too tight.
