Tor Arne Vestbø 04b2006f 2025-02-03T11:53:46 Remove outdated documentation note about CT operating in 96 DPI As extensively discussed and documented in #1484, Core Text does not operate in 96 DPI. Core Text doesn't actually have a concept of DPI internally, as it doesn't rasterize anything by itself, it just generates vector paths that get passed along to Core Graphics. In practice this means Core Text operates in the classical macOS logical DPI of 72, with one typographic point corresponding to one point in the Core Graphics coordinate system, which for a normal bitmap context then corresponds to one pixel -- or two pixels for a "retina" context with a 2x scale transform. As of f401f85a5a3ec4ab9c28012a0bfe713d7ee96951, we no longer apply any assumptions in HB about the target DPI being different than the 72 DPI used by CT, for example to account for the Web's standard of 96 DPI, so let's remove the documentation that still indicated this was necessary.
