Image Upload uses wrong size when sending to editor

As discussed at http://wordpress.org/support/topic/53640:

The code on lines 81-85 in wp-admin/inline-uploading.php appears to determine the size of the thumbnail file that WP generates:

if ( $imagedata['width'] * $imagedata['height'] < 3 * 1024 * 1024 ) {
if ( $imagedata['width'] > 128 && $imagedata['width'] >= $imagedata['height'] * 4 / 3 )
$thumb = wp_create_thumbnail($file, 128);
elseif ( $imagedata['height'] > 96 )
$thumb = wp_create_thumbnail($file, 96);

But from what I can tell, this code does not actually affect the dimension attributes WP uses when inserting the image. For example, changing the code in inline-uploading.php will result in a thumbnail file with larger dimensions on your server, say 256x192, but when browsing and inserting the thumbnail into the post, WP will still apply the code using something like <img src="pic.jpg" width="128" height="96 />. This is where admin-functions.php comes into play.

Lines 1771-1778 look something like this:

function wp_shrink_dimensions($width, $height, $wmax = 128, $hmax = 96) {
if ( $height <= $hmax && $width <= $wmax )
return array($width, $height);
elseif ( $width / $height > $wmax / $hmax )
return array($wmax, (int) ($height / $width * $wmax));
else
return array((int) ($width / $height * $hmax), $hmax);
}

and lines 1863-1870 look something like this:

function get_udims($width, $height) {
if ( $height <= 96 && $width <= 128 )
return array($width, $height);
elseif ( $width / $height > 4 / 3 )
return array(128, (int) ($height / $width * 128));
else
return array((int) ($width / $height * 96), 96);
}

Now I've tinkered around with it for a while, replacing the 128 and 96 values with larger integers. I have had limited success in which inserted images now appear with their original dimensions; however, when opting to insert thumbnails, the "thumbnails" are also stretched to the larger dimensions of the original, which causes them to be massively pixelated.

I am by no means up to snuff on PHP and coding in general, so I have a feeling that if someone more knowledgable were to take a look at the source in these files, there is a way to alter the dimension integers appropriately so that original images and thumbnails are displayed with their correct dimensions respectively.

innerHTML wasn't responding to changes in src attribute.

This patch removes height and width attributes during Send To Editor function, and fixes image to be sent with the proper src attribute.

(In [3407]) Send to editor fix ups. fixes #2199

I just installed the latestest update 3407 and im getting these.
