When I zoom in using Ctrl+Mousewheel the document just zooms in. It would be better if it zoomed towards the mouse pointer, like Gwenview does, so you can just hover the area you want to enlarge and Ctrl+Mousewheel without needing to scroll where you want to look at all the time.
(Btw the new tiled rendering is awesome)

Reproducible: Always

Steps to Reproduce:
1. Open a big PDF file (such as public transport lines or a map)
2. Move your mouse over a town/station in some corner of the document
3. Zoom in using Ctrl and your mousewheel
Actual Results:  
The document will zoom towards the center of the document

Expected Results:  
The document will zoom towards your mouse cursor so you will eventually have the desired town/station magnified.
