Five fixes that surfaced from an outside audit of the code. One of them
matters to everyone who draws.

Palm rejection works now

Android's hidden TOOL_TYPE_PALM constant is 5. The app compared against 6,
so since the feature was added no palm was ever filtered: a hand resting on
the tablet reached Linux as a finger and scrolled or clicked. With the filter
live, a finger that Android reclassifies as a palm mid-gesture is lifted on
the host instead of left pressed, and every DOWN that was forwarded gets its
UP.

Also fixed

  • A second daemon started as plain uscreen (no subcommand, which means
    start) was not recognised as one and could run alongside the first, both
    fighting for the capture device.
  • The helper's BT.709 chroma coefficients summed to −1, so pure greys and
    white carried a one-step blue cast.
  • The generated EDID is written to a temporary name and renamed into place;
    a crash mid-write can no longer leave a truncated file that every later
    start would use.
  • The app's frame-arrival ring index wraps instead of overflowing after 2³¹
    frames.

Still open

The Galaxy Tab S10 FE+ black screen
(#10) is not touched by this
release. 1.2.4's decoder ladder and timestamp change are waiting on a log
from that tablet.

Update both halves together. Files: .deb, .rpm, PKGBUILD archive,
portable tarball, uscreen.apk, SHA256SUMS.
