From 360b72ade0acfa655a3740b638a0cc8e23238a05 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 14:59:21 -0300 Subject: The GUI draws in tiers from the regions; pane chrome moves with its pane Stage 8 of docs/render-pipeline.md. The frame is drawn in groups: tier 0, one per track in paint order (tiers 2 and 3), tier 4 (notices, then guides and the debug box), tier 5 (bar cursors), each cells, images, decor. Decor (rules, rails, thumbs, grip marks, spines, the workspace and column rules, the bottom band, notice rules, bar cursors) is whole-pixel rects through the new decor.frag over ui.vert, so it carries its track's transition and clip. A closing pane's chrome comes from Surface.previous_regions. Deleted: taglineBaseRgb, topbarPaneBorderHeight, bottomTaglinePresent, frameChromeBg, cellBackgroundIs and the rail inference, paneGripCell's scan, transient_on, PaintPlan. One cover map (coverFrame) is marked from the layers and regions once a frame. New regions column, guide and debug; Surface.chrome is the palette, carried in wire v8 (not shipped yet), so an attached GUI draws the same chrome (test). A per-instance clip replaces the vertical transition's scissor. Goldens: 01-12 byte-identical. 13-17 differ only past the grid: the image pass left its scissor at the grid's size, cutting rule ends, rail feet and the bottom band in the leftover pixels whenever a picture was on screen. 16-debug now shows the debug box, which a context-row layer had hidden. 18-mid-transition is new: virtual clock (PARDES_TEST_CLOCK in the GUI), PanelSlide Newcol with the picture, frame 6 of 12. Also: the GUI sleeps when idle instead of polling every 16 ms, and a minimized or occluded window sleeps through animation.
