Two changes that only make sense together, because the atlas is what the new layout feeds. Parley replaces cosmic-text for layout and shaping, and its editing model replaces the hand-written one. That is the larger win in edit.rs: parley addresses text by byte offset into one string rather than by (line, index), so `select_content`, `delete_between`, `insert_inner` and `newline` become ordinary string operations, and `iter_layout_lines`, `index_x` and `cursor_pos` -- which walked runs by hand to place the caret and the selection boxes -- are deleted in favour of `Selection::geometry` and `Cursor::geometry`. Those are bidi- and wrap-correct, which the hand-written versions were not. The file loses about 130 lines and gains Home/End. The atlas is what the TODO's "text resizing (per frame) is really slow" was about. Every string used to be rasterised into its own RgbaImage and uploaded as a whole texture whenever anything changed -- so a window resize re-rasterised and re-uploaded every visible string. Now a glyph is rasterised once per font, size and subpixel phase and shared by every string containing it, and a resize re-emits quads without touching the GPU's copy. The tabs example says so directly: its `views` counter, the number of texture views bound, goes from 6 to 1. Supporting pieces: a GLYPH primitive that samples a sub-rectangle and tints it, since the existing texture primitive samples a whole texture; a Patch texture update, because re-uploading a 4 MB page per glyph is what an atlas exists to avoid; and GpuTextures now keeps its Textures, as a view cannot be written through. Two bugs found on the way. `primitives!`'s @count rule recursed with commas while matching space-separated tokens, so it only terminated for exactly two primitives -- adding a third hit the recursion limit. And Color had no Default, which parley's Brush requires. Drops cosmic-text and unicode-segmentation, and with them two nightly feature gates that nothing uses any more: portable_simd (the old glyph compositing) and gen_blocks (the deleted line iterator). Eleven gates left. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
