[ros-diffs] [cfinck] 41666: - Give the "windows" module a more meaningful name. It's now called "optional" as it started to contain other stuff apart from Windows native libraries. - Add an optional file reference to the Systema font for Japanese text. The Japanese ROS GUI is already using it. This is probably just an intermediate solution as the font is Japanese-only (no Chinese or Korean support) and might not fit that well for dialogs, but it should serve us well for some time.
