# scripts/test-gfx.sh — automated graphics-layer verification.
#
# The cursor overlay compositor is the core of the GUI path: the shadow
# holds true content, the display gets shadow pushes with the cursor
# painted on top at every push, and the cursor never enters the shadow.
# This test boots QEMU headless and runs `gfx check` — an in-kernel
# pixel self-test that reads back shadow *and* display pixels — plus the
# `gfx` demo scene. Cursor *movement* against injected mouse input is
# covered by test-mouse.sh; here we prove the compositor math.
#
# Usage: ./scripts/test-gfx.sh
# Env: OVMF, QEMU (same defaults as other test scripts)
#
