* [VDS] Cache mana symbol renders and skip redundant resizes - Render each mana symbol once at a bounded master size and derive every requested size from the cached master, avoiding repeated full-size SVG rasterization on the GUI thread - Share scaled results through a process-wide cache keyed by symbol and size, so repeated widget creation and rescales don't redo the work - Skip redundant resize work in ColorIdentityWidget and ManaSymbolWidget when sizes did not change Took 8 minutes Took 50 seconds * Move to pixmap generator Took 8 minutes Took 4 seconds --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>
