Re: Changing the representation of rectangles in platform code

It's not very easy to reason about overflow issues with our current representation. This means that we currently just pretend that they don't happen. The idea for changing the representation came up in response to a security bug where we didn't really have a better solution. Changing to x1, x2, y1

It looks like the current one should already be as the the AssignASCII will be inlined into the caller and then the strlen can be inlined as well. -Jeff On Sun, Mar 1, 2015 at 7:04 PM, smaug wrote: > On 03/02/2015 01:11 AM, Xidorn Quan wrote: >> >> On Mon, Mar 2, 2015 at 9:50 AM, Boris Zbarsky

Re: Intent to implement and ship: Unprivilaged WEBGL_debug_renderer_info

I'm concerned this will discourage websites from reporting WebGL issues because it will be easier just to block whatever device has the problem they're running in to. This creates an additional burden on the web developer and essentially creates the user agent problem all over again, but at much wo

We're working on making all of the tests green for GTK3. This means that we could be changing the default linux configuration to GTK3 as early as FF42.
