"""Spec for the re-authored data/ui/OPTS_SWD (catalog handle 0x1003f).
Same window/dialog as the original, grown from 13 to 23 fields: the original
Music/FX/Detail rows plus FILTER, SCANLINES, RESOLUTION, FULLSCREEN and
ASPECT rows and their selection icons. Window-relative coordinates assume
the window at x=60, y=6, 200x188 (320x200 screen space).
Layout (window-relative):
y=8 OPTIONS title (field 8)
y=20 panel bumpin behind rows (field 2, 5,20 190x100)
y=24 DETAIL row + PIC1 (fields 6, 3)
y=40 FILTER row + PIC4 (13, 18)
y=56 SCANLINES row + PIC5 (14, 19)
y=72 RES row + PIC6 (15, 20)
y=88 FULLSCR row + PIC7 (16, 21)
y=104 ASPECT row + PIC8 (17, 22)
y=122 MUSIC VOLUME label (9)
y=131 music slider view/track (11, 0)
y=146 SOUND FX VOLUME label (10)
y=160 fx slider view/track (12, 1)
y=174 EXIT button (7)

"""Dump and build Raptor .SWD dialog assets.
On-disk format (little-endian), mirrored from src/swdapi.h:
SWIN header 120 bytes <8i 16s 16s 14i>
SFIELD32[] 148 bytes <8i 16s 16s i 16s 15i i> (sptr -> PlaceHolder)
text blob NUL-padded strings
Each TEXT/BUTTON/INPUT/DRAGBAR field stores its text at `txtoff` RELATIVE
TO ITS OWN RECORD (SWD_ReformatFieldData compensates the 64-bit struct
growth with `(numflds - i) * 4`, which only closes under that reading).
Other field types never dereference txtoff.
Modes:
dump <file.swd> pretty-print SWIN, fields, text blob
build <spec.py> <out.swd> assemble a .swd from a Python spec
Spec module contract (see tools/opts_swd_spec.py):
from swdbuild import BUTTON_TEMPLATE, ... # clone-source records
SWIN = {...} # all 24 ints + name/item_name strings
FIELDS = [ {...}, ... ] # {**TEMPLATE, **overrides}; "text_index" links
