# check-draw.sh - Host gate for the shared line and circle fallbacks
# (src/core/draw.c) at the far ends of their coordinates: the BLANK port
# built with the host cc, and tests/host/drawHost.c drawing a line whose
# ends are 40000 apart, a nearly vertical one as long, a circle of radius
# 20000 crossing the stage, and one far off it near the int16_t limit, each
# checked against the true geometry. (16-bit state once made the first two
# never finish and the third plot pixels far from itself.)
#
# Usage:   scripts/check-draw.sh
# Exit:    0 PASS, 1 FAIL
