The word HEOS at the top of the panel becomes the mark itself, and the
home-screen icons are rendered from the same file so there is one place
to change it. All white on transparent: the panel is dark, and iOS lays
a transparent apple-touch-icon over black.
make_icons.py no longer draws its own glyph -- it rasterises logo.svg
with headless Chromium, which is heavier than the old arithmetic but the
only way to render real paths without a system SVG library. The PNGs are
committed, so it only has to run when the logo changes.
