Current behavior:
Our CPVT_GenerateAP::Generate*AP() functions do not get called as
long as the annotation dictionary has an "AP" entry.
Problem:
We always need the "N" entry in AP dictionary to display an
annotation. Even though the spec requires "AP" dictionary to have an
"N" entry for normal mode appearance, in case of a malformed pdf
with "AP" but without "N" in "AP", we won't be able to display the
annotation at all.
Fix:
Always check if "AP" has "N" entry to decide whether AP needs to be
generated. If not, then we still need to generate AP, and add to the
AP dictionary under the key "N".

This function copies the selected text from a form text field or
form combobox text field into the buffer parameter and returns the
length of the selected text string. When buffer is a nullptr or
buflen is less than the length of the selected text, this function
does not modify the buffer and only returns the selected text length.

When a Shading is created we have both a ShadingPattern and a
ShadingObject. The ShadingPattern is a ref-counted object that is stored
in the CPDF_DocPageData. The ShadingObject, when we have a tiling
pattern parent, is stored in the CPDF_Form of the tiling pattern.
Currently during destruction it is possible for the ShadingPattern to
get cleaned up before the ShadingObject which causes the UnownedPtr
probe to fire. This CL loops over all patterns and for each Tiling
pattern forces the CPDF_Form to get cleared. This then removes the
ShadingObject before we remove the ShadingPattern.

This CL uses the following algorithm for improving substitute font spacing (we
are assuming the text layout is horizontal):
* Calculate PDFWidth, the width that the PDF says the glyph should have.
* Calculate FTWidth, the width calculated by freetype for the glyph, using the
substitute font that we'll use to render it. Note that some embedded fonts have
PDFWidth == FTWidth + 1, so we consider that to be matching widths.
* If PDFWidth > FTWidth + 1 , move the x coordinate by the difference / 2 so
that the glyph is rendered in a more centered spot and the text looks better.
* If PDFWidth < FTWidth, transform the glyph horizontally by PDFWidth / FTWidth
so that the glyph gets compressed and does not overlap with surrounding glyphs.
