[whatwg] Images preprocessing

[Filip Likavcan]

Hi,

I was thinking about some preprocessing of images before they are
uploaded to server. Typical example is unexperienced user who wants to
upload whole set of photos from birthday party. Every photo has
unnecessary huge proportions and will be resized immediately after
upload. What if UA could be asked to resize images before upload thus
saves banwidth, server resources, upload time, etc.?
