Firefox OS RIL (htsai)

<Read Only>

1. https://wiki.mozilla.org/TPE_RIL_team/2014-07-29

GFX (milan)

• Desktop
  • Linux: bug 1015218 - Use Cairo image surfaces and XShmPutImage instead of XRender on GTK/Linux OMTC basic - landed. This will help us with getting Linux closer to other desktop platforms and be able to share more effort that benefits them all (by eventually moving to Skia.)

• B2G:
  • Looked at the home screen memory usage, and whether we have to switch to "four icons across" to help that situation. As of right now, four across helps compared to three across, but not enough to force us to do it, so the proposal is to go back to three, while maintaining the hunt for any less than efficient memory consumption.
