Text widths and heights were incorrectly reported by the Quartz device if the drawing context didn't exist yet (typically when drawing off-screen to a window that is yet to appear, see PR#18591).
The Quartz device could segfault in cases where paths with spaces are used in the new glyph drawing API. Thanks to Tomek Gieorgijewski (PR#18758).
