- Add ability to capture while normally playing - Calculate capture area based on coordinate transformations - Improve and simplify captureScreenshot function - Move dynamic library wrappers into libraries folder - Update capture.dll to support cropping and resizing - Recompile capture.dll with newer PureBasic compiler that uses C backend - Increase capture.dll worker threads to 6 - Increase capture.dll queue size by one - Add Round and Rounded methods to Vec2 - Split magic number XML files for easier debugging - Fix some EmmyLua annotations - And and fix some comments
