Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

* \brief Header: Hight-level mouse API.
|
|
*
|
|
* This is a thin layer over the low-level mouse protocol in lib/tty/mouse.h.
|
|
* The latter is oblivious to the regions on the screen and is therefore a
|
|
* bit hard to use in widgets. This layer translates the low level Gpm_Event
|
|
* into something that's easy to work with in widgets.
