- fix: polyline arc center sign was inverted (- → +) causing arcs to render on the
wrong side in LwPolyline and Polyline2D
- fix: store glyph strokes in local space with f64 origin so world_offset subtraction
uses f64 precision; prevents blocky text at large UTM coordinates
- fix: Face3D fill darkened to 45% so edge wires are visually distinct from fill
- fix: wire batch vertex buffer chunked to 256 MB GPU limit (was panic on large files)
- fix: gpu_face3d_edges changed from Option<WireGpu> to Vec<WireGpu> to support chunks

Spline entities now expose fit_points (or control_points when no fit
points are defined) as key_vertices, enabling Endpoint and Midpoint
snap to reach spline construction points.
TextStyle is_backward flag is applied by negating the width_factor,
producing horizontally mirrored text. is_upside_down rotates the text
180°. Both tessellate_text_ex and text_local_bounds now handle negative
width_factor without clamping it to zero.

Text/MText values now correctly handle DXF special-character sequences:
- %%d → °, %%p → ±, %%c → ⌀, %%nnn → Unicode scalar (resolved in tessellation)
- %%u / %%o toggle underline and overline strokes for TEXT entities
MText decoration codes (\L/\l, \O/\o, \K/\k) were previously consumed
as argument-bearing codes, silently eating the decorated text. Fixed
strip_mtext_codes to keep them as zero-width markers; tessellate_text_ex
now emits actual line strokes (underline, overline, strikethrough).
measure_mtext_chars and word_wrap skip markers so line widths are correct.
