debugDelegateAll property
Debug: route every paint through the fallback (no strips at all) to isolate tape/pipeline effects from strip rasterization quality.
The debug-delegate flags change ROUTING, so they force local binning: callers must not feed a device a worker-binned plan while any of them is set (the worker isolate carries its own statics and would bin the full routing, desyncing flush ordinals).
Implementation
static bool debugDelegateAll = false;
