quoije 0a16d3d3ec Fix RCO menu coordinates and smooth video pacing

RCO object positions are screen-center with +Y up, but the renderer drew
them as top-left, pushing menu items off-screen. Convert to top-left in
the 480x272 design space before drawing.

Also use precise parkNanos pacing and reuse per-frame ARGB/WritableImage
buffers to remove the 1.4MB allocations per video frame.

useless-umd-player

a standalone player for PSP UMD Video ISO images: open a disc, render its real menu, and play the movie (H.264 video + ATRAC3+ audio) with mouse and keyboard/media-key controls.

Status: early development. Currently implemented: ISO 9660/UMD reading, param.sfo metadata parsing, and file listing.

Build

Requires JDK 21 (Gradle auto-provisions it via the Foojay toolchain resolver).

./gradlew build

Run

./gradlew cli:run --args="dump /path/to/disc.iso"
