Description of bug

Non-Integer Thumbnail Sizes Break API Calls

Steps to reproduce

1. Try zooming out several times in your browser.
2. Reload a DNN Page with the Assets page of the Persona Bar open.
3. If the thumbnails fail to load, look in the network tab for the failing calls.

It is easy to reproduce the failed API calls with non-integer parameters: make an API call to http://{your dnn install}.dnndev.me/DnnImageHandler.ashx?mode=securefile&fileId={a file id}&MaxWidth=74.98&MaxHeight=42.01

Current behavior

API calls return with HTTP 500

Expected behavior

API parses the non-integer parameters and returns thumbnail based on rounded dimensions
