ReportRenderer.render Method
Generates the view. If isProgressiveLoadingEnabled is false
the view is generated in full, otherwise this attempts to generate at least enough of the view
to reach desiredWidth and desiredHeight based on the unadjusted template sizes.
The result will be at least as large as the desired size if possible. After rendering the desired size is
updated to equal the view's current size.
