Render the MTEXT background (never drawn before — the flags were only shown read-only in the panel) and make it editable. - Text arm emits an opaque fill_tris rect behind the glyphs: flag 0x01 uses the entity background colour, 0x02 uses the canvas colour (a wipeout-style mask). Box = glyph bounds padded by (background_scale - 1) × text height. - Text frame (flag 0x10) draws a closed rectangle in the text colour around the same box. - Threaded `bg_color` into `tessellate()` (+ all callers and the MultiLeaderTess trait) so the mask can use the drawing-window colour. - Properties: "Background mask" is a Off / Fill / Mask dropdown, "Background color" is its own colour picker (independent of the entity colour — new PropBgColor* messages; picking a colour switches to Fill mode), and "Text frame" is a checkbox toggle. Edits re-tessellate so the change shows live. Renders via the face3d fill path, so the fill shows with FILLMODE on (same as MLEADER background fill); the frame is a stroke and always shows.
