Title: NPE in BlockBox

Just added a null check in calcCanvasLocation. Exception was happening when a paginated table with headers that had a row with a floating div in it was spanning pages. Just adding the null check seemed to cause the page to display fine.

Sample that causes the exception:
```HTML

test header

test cell

```
