Baseline shift now moves a character in the line's frame, outside
Character Rotation, so a positive shift moves a character up from its
line at any rotation, and the character turns about its shifted pen
position. The Touch Type tool splits a drag into its part along the line
(kerning) and its part up from the line (baseline shift) at every
rotation; before, within about 6 degrees of a quarter turn it dropped
the cross-line part.
Characters that already combine a rotation with a baseline shift are
drawn in a new position. Their stored values do not change.

Character Rotation turned a glyph's baseline shift and scaling with the glyph, and the Skew path effect slants a glyph's height away from the path's normal, so the x-height guide moved off the glyphs. Each positioned glyph now carries the transform that removes its Character Rotation (PositionedGlyph::unturned), and the guide goes through the glyph's x-height point placed without it, measured across the baseline. Snap to Glyph also takes Smart Guides being on in the tools, as View › Snap to Glyph already does in the engine.
