2018-10-18	Push/pop the graphics state stack when flattening.	Lei Zhang
	When FPDFPage_Flatten() manipulates a content stream, it replaces the content stream with a content stream array. The first element in the array is the original content stream and the second element in the array is the flattened annotations content. To make sure the original content stream's graphics state stack does not affect the flattened annotations, FPDFPage_Flatten() rewrites the original content stream to be: q $contents Q When FPDFPage_Flatten() manipulates a content stream array, it just appends the flattened annotations as a new element in the array. This may result in graphics state stack leaking out. To fix this, wrap the content stream array to be: ["q", $content1, ..., $contentN, "Q"] And then append the flattened annotations.
