PDF internals should always use dots as a decimal separators

Currently Qt creates blocks like this when exporting PDFs:

/Rect [66,960000 765,260000 103,983750 772,580000]

In my case, using commas (which seems to depend on locale) causes Evince to not draw a rectangle correctly. My locale in ru_RU.UTF-8.

I attach two PDF files, first one is generated by QPrinter where I printed a QTextDocument with contents:

<a href="http://www.google.com/">Google</a>

The link isn't working in Evince.

Second one differs from first one by using dots instead of commas, and the link works.
