PHLEGM v8 Revision r88 - GUI Skin DITH / FILL
===========================================

Revision: r88
Timestamp: 2026-1011-1649-1296

Syntax:
GUI SKIN <STATUS|<MONO|ARGB>|<TREE|ICON>|<FLAT|ANIM>|<DITH|FILL>|<CHAR|FONT>>

Default: MONO / TREE / FLAT / FILL / FONT

DITH: 4x4 ordered Bayer screen of CHOP model surfaces at GUI paint time.
Brightness controls dot density (darker surfaces denser).
Black CHOP feature wires stay solid and transparent exterior stays clear.
Works with both MONO (black/transparent) and ARGB (full color).

FILL: prior solid continuous CHOP rasterization; no dithering (default).

All five GUI skin dimensions can be changed independently.
On a raster change, GUI icon caches reset on Windows and Linux.
The source CHOP ARGB frames remain unchanged.
Instruction definitions upgraded to embedded-definition-version=24.
DITH/FILL appear under GUI SKIN / Raster at the bottom of Tree/Icons.

Validation: static-source consistency + Bayer mathematical cross-check.
Native FreeBASIC Windows/Linux compile and visual runtime tests pending.
