2018-05-31Make XFA pixel tests more stablechromium/3447Ryan Harrison
When generating PDFs using the fixup script and a .in, specify them to to use Ahem.ttf as the text font. Ahem is a font designed to reduce flakiness in pixel tests due to font rendering differences between platforms. Specifically the glyphs in the font are standard size black boxes, so though the specific text content cannot be easily compared, things like layout and high level changes to the content can still be tested. Testing things like specific text changes should be done via an embedder test, where the strings in the elements can be extracted and inspected. The font itself is is CID type 2 font, which is relatively complex to correctly embed in a PDF due to subsetting and other features. Instead of embedding it in the generated PDFs, which was originally attempted, it is being supplied to pdfium_test via the --font-dir flag. This flag overrides where the binary looks for system fonts. This works correctly on Mac and Linux, but not on Windows, which is why that platform remains suppressed.

2018-05-18Fix issues with XFA font loadingRyan Harrison
This fixes two partially interrelated bugs with font loading in XFA documents. First, it adds falling back to the builtin fonts if there are no viable embedded or installed font for the top-level XFA font manager. Additionally it changes the load font code path in CXFA_FWLTheme to use the top level XFA font manager, instead of the one that just handles the system installed fonts. The main visible issue that this patch fixes is that currently using --font-dir with pdfium_test on a XFA PDF can cause text to not be displayed in widgets and/or NOTREACHED asserts. This occurs if there isn't a needed fonts embedded in the document or in the font directory, since currently PDFium will not correctly fall back to the builtins.
