Description
When rendering the provided PDF file the following exception is thrown:
WARNING: Error parsing content stream.
java.util.EmptyStackException
at java.util.Stack.peek(Stack.java:102)

It is possible this is causing the first page of the PDF to render with missing content (half of the page) as well as missing borders.

We have some specially character handling for the negative symbol which can be duplicated for the positive symbol. Updated Lexer, marking as fixed.

The PDF in question has some very odd syntax that is for lack of a better word malformed. The following rectangle definition:
9.35 551.74 17.99 +2.39 re f
The plus sign is used for the last coordinate of the rectangle which is outside the spec. This shouldn't be to hard to adjust for though, will add a parser fix.
