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.

* This test was originally created to test _cairo_fixed_from_double.
|
|
* cairo_pattern_create_radial was selected as the entry point into
|
|
* cairo as it makes several calls to _cairo_fixed_from_double and
|
|
* presents a somewhat realistic use-case (although the RADIALS_COUNT
|
|
* isn't very realistic).
