Texture fill e2e checks pick the right image in a full run (#186)

CI run 217 for 592ea94 failed three checks in block 47i. In the full
run the texture list is longer than in a single module run, so the
picker click missed "halves" and the texture stayed empty.

- The check now types "halves" into the menu search field and picks
  it with Enter, independent of the list length.
- FIND_HALVES looks the image up by name. Matching only by size had
  picked the 32 px image "wedge" in the full run.
- The texture fill check forces a redraw before reading pixels. After
  the work of earlier modules the vector tab does not redraw once the
  texture has loaded. That bug is tracked in #196, and the forced
  redraw goes away with it.

Tests:
- ./check.sh: CHECK EXIT 0
- npm run build: BUILD EXIT 0
- GM_STEPS=47 (fresh seed): ALL PASSED, 54 checks
- Full run not repeated locally. CI decides.
