Could this be solved in workers?
x) Create canvas, set to desired size
x) Create 2D context
x) Create imageData object
x) Create a WebGL framebuffer object
x) Attach texture as color target to framebuffer
x) read back pixels into canvas2d's imageData.data member
x) ctx.putImageData into the canvas

Sorry if these have all been discussed before. I just read the File API for
the first time and 2 random questions popped in my head.

Sorry I don't have anything to add to the main discussion points but I want
to point out that this should NOT be limited to the canvas tag.
There are whole game engines that work on nothing but manipulating DOM
elements with z-index and setting style.left and style.top. I can imagine
plenty of ot

Sorry if this has been covered before.
I've been wanting to write an app to download images from photo sites and
I'm wondering if this use case has been considered for the FileAPI wrt
Directories and System.
If I understand the current spec it seems like their are some possible
issues.

I'd like to see if there is some consensus on this issue. Various people are
anxious to see this happen in more browsers.
A couple of questions came up for requestAnimationFrame

I'm sorry if I'm not familiar with all the details of how the widgets spec

It seems like widgets have 2 uses
#1) As a way to package an HTML5 app that can be downloaded similar to a
native
executable
#2) As a way to package an HT
I'm not sure if this is the correct place for this but:
Has there been any discussion of adding an element.onresize event?
The issue that has come up is the canvas tag, in 2d or 3d, when the canvas
changes its displayed size, a webapp might want to respond by changing
the size of the internal rep
I posted something about this in the whatwg list and was told to bring it
here.
Currently, AFAIK, the only way to do animation in HTML5 + JavaScript is
using setInterval. That's great but it has the problem that even when the
window is minimized or the page is not the front tab, JavaScript has no

How about this?
Why make a new API for getting the contents of a file (local or otherwise)
when we already have one which is XHR?
What if FileList was just array of File objects where each File object is
just a URL in the format
"filedata: uuid, filename"
Then you can use that URL anywhere in H

I hope I'm in the right place.
I'd like to propose / suggest that XMLHttpRequest be extended to handle
gzipped tar files. Usage would be something like
var req = new XMLHttpRequest();
req.onfileavailable = myOnFileAvailable;
req.open("GET", "http://someplace.com/somefile.tgz";, true);
req.send();
