MobileGL trace replay

This directory builds a Linux command line replay runner for apitrace files. It is an integration testing infrastructure of MobileGL.

The bundled fixtures cover:

• OpenRA: sourced from GL4ES' apitrace corpus.
• minecraft-1.21.4-startup: captured from Minecraft 1.21.4's startup screen.
• minecraft-1.21.4-main-menu: captured from Minecraft 1.21.4's main menu.

Build from the MobileGL repository root:

cmake -S . -B build-test -G Ninja \
  -DMOBILEGL_BUILD_TEST=ON \
  -DMOBILEGL_BUILD_BENCHMARK=OFF \
  -DMOBILEGL_BUILD_TRACE_REPLAY=ON
cmake --build build-test

Run the fixture tests:

ctest --test-dir build-test -V -R 'MobileGLTraceReplay\.'

Run the CLI directly:
