at some point we need to convert the generic HUD to sue the canvas - not a job I'm looking forward too - so I'm likely to steal any ideas and pieces I can to make my life easier. If anyone who actually uses HUDs wants to help with such an effort, please get in touch with TheTom and/or Zakalawe[http://flightgear.org | at some point we need to convert the generic HUD to sue the canvas - not a job I'm looking forward too - so I'm likely to steal any ideas and pieces I can to make my life easier.

The Canvas subsystem is flexible enough to re-implement existing 2D rendering related features, such as the HUD system or the 2D panel system, in scripting space, so that legacy C++ code can be incrementally replaced with a more accessible and more maintainable version in scripting space, i.e. as part of the base package - while ensuring that the 2D rendering backend is increasingly unified, using the Canvas subsystem as the common rendering backend. Once a standalone mode for the canvas system has been implemented, all systems making use of the canvas backend will automatically support standalone (FGPanel-analogous) rendering. | The Canvas subsystem is flexible enough to re-implement existing 2D rendering related features, such as the HUD system or the 2D panel system, in scripting space, so that legacy C++ code can be incrementally replaced with a more accessible and more maintainable version in scripting space, i.e. as part of the base package - while ensuring that the 2D rendering backend is increasingly unified, using the Canvas subsystem as the common rendering backend.
