> Should I commit the partial work that I have done ? Yes. Add it to the build if it compiles properly and don't if it doesn't. We've had a problem in the past with people not checking in their work, getting hit by Real Life(tm) and their work never sees the light of day. > There are also some inline functions which work with clipping_rects, > that should be put in a private but "accessible" header (private/ interface ?), since I guess they can be interesting even for our app server. Sure. private/interface would be an appropriate place for them. The server uses BRegions for most of the drawing stuff, but they might come in handy for when I need to implement stuff for Game Kit support. --DW
