<198982749+Copilot@users.noreply.github.com> Date: Wed, 18 Feb 2026 23:17:49 +0000 Subject: [PATCH 08/11] Make ICairoShim methods const, add Pango support, remove cairoContext - Made all ICairoShim methods const for better const-correctness - Added pango() method to ICairoShim for text rendering support - Removed cairoContext() method as per review feedback - Updated CairoShimCairo to maintain Pango instance - Fixed operation.cc and intOp.cc to use cairoShim methods instead of raw cairo - Updated Item::draw and displayTooltip to use cairoShim.pango() - Changed all draw method parameters to const ICairoShim& - Removed unnecessary cairoShimCairo.h include from item.cc - Added ICairoShim.h include to wire.h Co-authored-by: highperformancecoder
