Apply coordinate mapping (VIEW/WINDOW) to POINT(x,y) function so it returns correct pixel values when WINDOW is active. Remove unused palette[] array from graphics.c (Sixel encoder uses palette_map[] directly). Expand view_window.bas test to cover WINDOW SCREEN mode, VIEW+WINDOW combination, and PMAP inverse mapping. Fix CI test count in docs.

Tests
66 test programs in tests/programs/, plus 4 classic interactive programs in
tests/classic/ (Hamurabi, Lunar Lander, Gunner, Diamond from David Ahl's
BASIC Computer Games).
Run the full automated suite:
bash tests/run_tests.sh
Each test has a 5-second timeout. 62 tests have .expected golden files
for output regression detection. Three timing-dependent tests (datetime,
on_timer, timer_stop) and one visual test (color_test) run without golden
comparison.
Compatibility Testing
Compare output against real GWBASIC.EXE running under DOSBox-X:
# Generate .expected files from GWBASIC.EXE (requires DOSBox-X Flatpak)
bash tests/run_compat.sh --generate
# Compare gwbasic output against .expected
bash tests/run_compat.sh
CI
GitHub Actions runs on every push to main and on pull requests. The workflow
builds the project with PulseAudio support and runs all 66 test programs.
