PHLEGM v8 Revision r89 - CHR Tree Renderer
========================================

GUI SKIN TREE and GUI SKIN CHAR may both be enabled at the same time.
All tree labels (roots, branches, leaves, and lazy media nodes) use the
Packard Bell 8x8 CHR font from drawchr.lib when CHAR mode is selected.

Windows: native SysTreeView32 preserves its item model, branch graphics,
scrolling and selection; NM_CUSTOMDRAW postpaint replaces native label text
with CHR glyphs, using a light selection backdrop for the opaque-black mask.
FONT restores native drawing. Tree invalidation follows font switches.

Linux: existing CHR pixbuf cell renderer supplies tree glyphs. Its visibility
is exclusive with the native GtkCellRendererText and the tree is explicitly
queued for redraw on font changes.

No changes to GUI SKIN syntax: five independent color/view/presentation/
raster/typeface settings remain unchanged. Default remains MONO / TREE /
FLAT / FILL / FONT.

Native FreeBASIC compilation and live visual validation are still required.
