Memory leak (fix)

[GoogleCodeExporter]

What steps will reproduce the problem?
Using the PdfWrapper class from C# will result in severe memory usage when 
repeatedly rendering the PDF. I am using .NET 4.0.

Specifically:
I found that:
1) when using mupdf the mupdfEngine is not deleted (result: pdf file cannot be 
deleted until application is closed)
2) destructor from AFPDFDoc never called due to missing cast

Find attached a SVN patch that fixes those problems. It also fixes a duplicated 
call of Dispose() of PdfWrapper (which never showed up due to the first two 
problems).

I also attached a very slim test program (that is only Form1.cs of it; just 
create a form with a PictureBox and 4 Buttons using default names VisualStudio 
assigns)

And finally there is a "patch" which creates a fine PdfLibNet.dll for .NET 4.0
