# check-indexed.sh - Host gate for jlSurfacePasteIndexed and
# jlSurfaceSnapIndexed: the BLANK port built with the host cc, and
# tests/host/indexedHost.c pasting and snapping edge-case and seeded random
# rectangles (odd columns, both edges, doubleWide bytes cut by an edge, rows
# off both ends, the int16_t limits), each checked against a reference made
# one pixel at a time with jlDrawPixel and jlSamplePixel; then the planar
# ports' paste and snap (src/m68k/planarIndexed.c) on host buffers in both
# planar layouts, separate and ST-interleaved.

# Usage:   scripts/check-indexed.sh
