figure() reached an MXP client as text art alone. Figure.Draw marked its picture only for a terminal that draws pictures in cells (PictureCellsMarkup, under LayoutContext.Pictures), so MXP, Pueblo and BBCode had no picture to write. PictureCellsMarkup is folded into ImageMarkup as an optional Row (PictureRow: row, rows, columns), and a figure with an address always marks its rows with it. MXP, Pueblo, HTML and BBCode write the element once (ImageMarkup.StartsPicture) and keep the figure's other cells blank, so text beside it stays put; a client that refuses the element, or an HTML policy that refuses <img>, reads the art. The ANSI terminal path is unchanged apart from reading the row off ImageMarkup.

- Around line 35-36: Update PictureRows to return null when the art has zero
width, so Draw uses its existing marked-description fallback instead of emitting
unmarked rows or skipping available pixels.

A figure whose art held only line breaks returned its rows unmarked, so no format wrote the picture. It now takes the description fallback, and a terminal with pixels draws in cells sized for the pane rather than none.

Before: a laid-out
Figurereached MXP, Pueblo and BBCode clients as its text art or its[description]only.Figure.Drawmarked its rows only whenLayoutContext.Picturesanswered, and then withPictureCellsMarkup, which only the ANSI writer read. An MXP client that answered IMAGE in SUPPORT got no<IMAGE>fromfigure().After: a figure's rows carry the figure's own
ImageMarkup, with a newRow(PictureRow(Row, Rows, Columns)) saying where in the picture each row sits. MXP writes<IMAGE>once on the first row, Pueblo and HTML<img>, BBCode[img], and the rest of the picture's cells are written blank, so text floated beside it stays in its column. A client the tag is not offered to, or an HTML policy that refusesimg, reads the art as before. ANSI with pixels draws in the same cells it used to. Art made of line breaks alone counts as no art.How:
PictureCellsMarkupis folded intoImageMarkup.Row, andImageMarkup.StartsPicture(context)is the one test every writer uses to write the tag once.Figure.Drawmarks its rows whenever the image has an address, with or without pixels. The element codec round-tripsRow.Notes:
PictureCellsMarkupis removed. It was listed inPublicAPI.Unshipped.txtbut went out in 2.12.0 and 2.13.0, so a consumer that names it breaks. SharpMUSH does not reference it and needs only the package bump.image()is not yet a one-row figure, so it still gets no terminal pixels. Left for a follow-up.Tests: 1095/1095 in
