imgui_xl

Dear ImGui XL — An enhanced community fork of Dear ImGui, focused on backend improvements, CI/CD fixes, sensors, and extended examples.

Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer-agnostic, and self-contained (no external dependencies).

Bug Fixes Summary

Merged upstream (3 PRs):

• Android CI — Pinned Gradle 9.4.1 via setup-gradle action, no binaries (#9467)
• OpenGL GL_UNPACK state — Backup/restore GL_UNPACK_ROW_LENGTH and GL_UNPACK_ALIGNMENT in UpdateTexture() to prevent caller state corruption (#9473)
• Android touch release — Clear mouse position on AMOTION_EVENT_ACTION_UP so buttons don't stay hovered (#6627)
• SDL2 soft keyboard — Restored SDL_StartTextInput()/SDL_StopTextInput() under #ifdef __ANDROID__ for on-screen keyboard (#7636)

Open PRs (2):

• OpenGL2 texture destroy — Defer destruction until UnusedFrames > 0, matching all other backends (#9475)
• Android backend cleanup — Move JNI keyboard/clipboard into backend, add display metrics, breaking change to Init() signature (#9469, under review by Omar)
