Ice Palace: dot cells, paint, and stashes for the new renderer

[samtcifihi]

Notation

• Cells are written x.y rather than x,y: the front end reads commas in a move as separating simultaneous moves, so a build of numplayers - 1 pyramids was split into one move per seat.

Rendering

• Every legend glyph is coloured through paint, which the renderer now asks for in place of the deprecated colour. Translucency moves into the fill slot, so outlines stay solid as before.
• The hand and Pool are laid out alike under either board, since both renderers now lay stashes out with the same step; the 3D-board-only layouts with placeholders and headroom go.
• In 3D the Pool is shown as nests, each holding at most one pyramid of each size: the renderer rests a column's pyramids on one base line by size, so several of a size in one column were drawn as one, and a spacer among them was an error ("Could not resolve silhouette tier").
• The 3D hand glyph puts the pyramid before its invisible click square, which the renderer reads for the pyramid's size, so hand pyramids rest on one base line.
• Black and White pyramids paint their outline and size pips in whichever of black and white contrasts with the body, so a Black pyramid shows its pips. The sidebar sends each pyramid as its legend glyph so the border reaches it too.

Playground

• Status glyphs are sized to the text; the renderer sizes an inline glyph's svg to 100%, which the wrapper's max-height did not constrain.
