If /EndOfLine is set for a CCITTFaxDecode stream, the image must start
with an EOL per the spec. Other readers seem to ignore all data up to
the first EOL in that case - instead of rejecting such images as broken.
Required for e.g. "1848 - 1d faxd doesn't start with EOL.pdf".

Broken in recent optimisations.

The symptoms were that, created annoations were in some cases not saved.
Some updated objects withing the document were not being moved into the
incremental-save xref section. That in turn was due to nodes within the
hierarchy of those objects not having their parent_num field set. The
objects falling foul of this problem were those held in object streams.
When any one object from a stream is cached, the whole stream is read and
all other objects from that stream are also cached, but only the initial
one has its parent_num set. This patch ensures that all objects from a
stream are accounted for. In fact, for the initially-requested object, we
now set parent_num twice, but that is harmless and the code to avoid doing
so wouls be an unnecessary complication.

This is the single largest hotspot in J11_acrobat.pdf on the pi,
by a massive margin.
J12_acrobat.pdf hits fz_paint_affine_g2rgb too.

If we want the alternative versions we can pull them out of git
later.

Previously there was a bug when parsing GoToR link annotations that had
a named destination. mupdf incorrectly attempted to resolve the
destination in the current document. Now the destination name is
present in the link objects returned to the application so it can
resolve any names for GoToR links in the remote document instead.

Set display timeout where the page number is shown, not in x11 main.
|
|
|
|
|
|
The scenario is that the user first displayed the page number (visible
for two seconds) and then searched while the page number was still
visible. The page number was automatically cleared when entering search
text, but the timeout for clearing the page number was never cancelled.
This caused an unnecessary redraw of the window while the search text
was still being edited.

The current code uses a hash table with linear probing. This means
that when the cache fills up, we have no alternative but to bin the
whole thing (or do an expensive rebuild).
Change to using a simple hash table with linked lists of bucket chains,
and additional LRU lists. This way we can ditch the oldest glyphs as
we need more space.

Use of the feature is currently enabled only in the case that a file
that already contains xref streams is being updated incrementally. To
do so in that case is necessary because an old-style xref is then not
permitted.
This fixes bug #694527

This allows us to "mudraw -F ppm -o /dev/null" etc.

If there is no text to select we return an array with a NULL in it
and this causes the code to crash. Simple workaround.

Based on a patch from Sebastian Neuser - many thanks.
Use mouse buttons 6 and 7 to do the same as 4 and 5, but with Y
rather than X being the default.

We should use the leading, if present, and if not present we should
probably use a value a little greater than the sum of the ascender
and descender, but this is definitely a step in the right direction
and improves the look of filled-in forms.

Prevously the true bounds of the glyph were used which didn't account
for the total area blocked out by a character

This initial commit doesn't entirely complete the task:
1) There are a couple of ucs<->winansi conversions left out,
2) The text displayed by the appearance string can slightly
overflow the annotation rectangle.

Ensure that only base14 fonts are used
Set BaseFont using the name from the font
Use WinAnsiEncoding
Derive the font size from the trm matrix
