Assistant: Set the url on created QNetworkReply objects.

WebKit needs this as a base url in order to resolve links in css for
example. If index.html is at the location doc/, and it loads a css
stylesheet at href="_static/first.css", and first.css contains

 @import url("second.css")

Then second.css should be found in _static, relative to first.css.

That only works if WebKit knows the requested url of the loading
document, so make sure that is set on the reply object.

This is a backport of part of commit qttools/e38ee135f3cf74f413dc7a3e4a9f97a6b5d903bf

Avoid out of bounds memory reads when scaling images

The calculation of the width/height required for the
scaling algorithm was prone to floating point rounding
issues, where the lower value got rounded down, the higher
one rounded up. This could lead to a situation where we
iterated over one more line/pixel in the line than we have
in the source image.

Correct this by passing the dimension of the source image into
the function and bounds checking the values before iterating.

Instead of using a list and appending / popping of elements, use
a vector of constant size and access via index to avoid
bookkeeping errors.
