PDF fixes/tweaks.
Fix 2 places where we were filling a stroked pattern rather than
stroking it.
Cope with being asked to run a NULL buffer.
If running a stream fails, warn and return what we have, rather than
giving up entirely. Should really set a return code for each render.
Only look at the Print flag bit for Print renders. Only look at the
View flag bit for view renders.
If we find an unexpected ) or > during object parsing, warn and continue
rather than giving up entirely.
If optional content groups are broken, render the rest of the page
anyway.
Previously indirect objects that point to another indirection would
cause a failure; now attempt to resolve these. We set an arbitrary
limit of 10 such redirections to avoid infinite loops.
