    With the help of Claude, exactly match RIPTERM ellipses

    I had assumed they used McIlroy for Ellipses, so could only get
    close... they had actually used the two-region Bresenham, the reason
    I didn't get that to match was that they apparently scale by 100 to
    "avoid rounding", so my truncation was wildly different.

    And fix arcs too!

    We actually needed to extract the trig tables BGI uses to get this
    to work out right... fighting with floating point was not the way.

    Much better bezier match

    replace per-iteration step/cnt division with accumulated
    t += 1.0/cnt.

    This produces the SAME ERROR I see from the RIPterm across obvious
    test vectors.

    The old code was "too correct", RIPterm appears to accumulate error
    and never correct for it.

    Clean up old use of a hack bit, use the new polyfill for the RIP
    command, clean up some comments, and get XOR working properly
    everywhere.

    Some more button fixups.

    1. !|1U missing <res> field - no longer draws the button (per RIPterm)
    2. Recessed inner corner pixels - removed explicit cc-colored corner
    pixels on inner recess border (RIPterm lets the bg lines overlap naturally) 3. Chisel inset height off-by-one — y2 - y1 + 1 → y2 - y1 since box.y2 is
    exclusive

    Handle thick ellipses better.

    It looks like when drawing a thick ellipse, it draws multiple thick
    line segments. Now that we have the Borland cos/sin tables, we can
    do that ourselves as a special case.

    Fix parse_mega() buffer overreads

    Many places were calling parse_mega() without checking the return
    value, then calling parse_mega() on the string AFTER the previous
    one. This means that on truncated invalid RIP sequences, ripper
    would read past the end of the allocation.

    This fix was complicated by the fact that the "last" item in a
    parameter list can be truncated as long as it has at least one
    valid byte in it.

    This now uses a vararg function and parses them all at once (mostly).

    More fixes.

    RIPterm doesn't render \x0e or \x0f at all. (perseid.rip)
    Fixed size is ALWAYS used for plain buttons.
    Fix stroked-font tabs.
    The actual movement after a glyph is drawn comes from the stroke
    data, NOT the width data. In SANS.CHR at least, the table has TAB
    with a width of 0, but it's actually 24 based on the stroke.
    Only use npoints for |p, |P, and |l

    More RIP tweaks

    Correctly handle the "selected" flag.
    This also makes selecting buttons match the RIPterm rendering.

    Support "highlight icon" buttons.
    This is what you're expected to use with radio buttons and checkboxen

    Fix paste clipping
    It clips at the bottom of the screen, rejects at the right.
