Self-asserting wx app (tests/apps/standalone/uipolish) with 8 checks:
clip-clear / clip-empty / clip-box (DC clip box reaches the canvas — the
collapsed wire-properties-panel bug), blit-origin (wxBufferedDC device
origin), mask-alpha (ConvertToImage carries wxMask — infobar close button),
scaled-dims (physical size for scaled bitmaps), checkbox-floor (selection-
filter density) and statbmp-best (bundle logical size — layer-panel icons).
The spec runs a default-DPR pass plus a deviceScaleFactor:2 pass that also
asserts the statbmp <img> ships the 32px asset at 16 CSS px.
Bumps wxwidgets for the CloneGDIRefData SOURCE_NONE fix the @2x pass
surfaced (empty statbmp data URL on hi-DPI).
