Trac: Increase preview file size limit

[melchoyce]

HTML preview not available, since the file size exceeds 1.0 MB. Try downloading the file instead.

Any chance we could get this file size increased? Makes it really hard to preview mockups in Trac, since they're often more than 1mb.

An example of this is ​https://core.trac.wordpress.org/attachment/ticket/45073/Upgrade%20paths.jpg which is displayed inline in the comments thread, but is hidden in the attachment view as it's too large.

Displaying a preview for .diff files over 1M would actually not be ideal (The larger a diff is, the more processing time it takes to convert to HTML), so what we need is something specifically for images I feel.

Perhaps we should instead turn off force-download for /raw-attachment/ for image mime-types and have the comments link images directly to the image rather than the attachment screen?

If we can't turn off force-download of images, a quick-and-dirty workaround is to link to WordPress.com Photon instead (which might actually be easier, as less Trac changes..) - ​https://i0.wp.com/core.trac.wordpress.org/raw-attachment/ticket/45073/Upgrade%20paths.jpg

That would be perfect!
