Hi everyone,
Just built a new RPM, image version 1276. This includes the new nav bar in Sugar look, Scott's blueprint canvas, and the implicit self tiles.
The ZIP file is available as usual from
but I have not published the RPM yet (it's on tinlizzie though).
The problem is that as soon as the sugar nav bar is enabled, there is a pause every second. The tiny car moves some steps, then stops, moves, stops. This is only visible on the XO, my desktop is too fast. Disabling the flap cures this.
MessageTally indicates that undoButtonAppearance is the culprit. It rebuilds the undo icon every second, which apparently is not a cheap operation. Maybe using an 8-bit bitmap with a colormap would be more efficient? To get really fancy we'd even need to support two colors plus alpha, because the original icons have a fill color, stroke color, and transparency info.
Also, on the XO the navbar looks tiny, I think each button must be 75x75 px.

Thank you!

Ouch.

Since the other apps don't show different buttons when they are disabled, we don't have to do that. Just Graying (cheaply) is ok. I'll make that modification.

Yes. There was some confusion about the size among Abe-san and me. I'll try to hook up the SVG stuff and FFI interface to Cairo by Kawamura-san to prerender these icons from SVG file.

Cool, thanks, looks good. I pushed 2.0.1283. I tested on the XO and it appears to work, so I made the RPM available by yum, and thus it will be in the next OS build (whenever that will be).
We should announce our improvements, probably to Walter for the weekly report. I think there was no status update from us since the original B2 build, and quite a lot was accomplished since then. Also mention that we'll gather in the OLPC headquarters in two weeks, perhaps someone wants to meet with us.
