Attempt to separate public API from internal functions.
|

Update xps path handling to cope with URLs.
Fix premature freeing of links.
Spot remote URLs and use appropriate link type.
|
|
Currently, this only works with local links.
When running the page, check for NavigateUri entries; if found,
and that page is not already marked as having resolved it's links,
add a new link entry to doc->current_page links. When the page
finishes running, mark the page as having resolved it's links.
This avoids the links being generated multiple times.
Update the mupdf viewer to use these links - but only AFTER the
page has been run.

Move coordinate space tweaks into pdf_ and xps_run_page, and provide
neutral pdf_ and xps_bound_page functions to return the page size as
a zero-origined bounding box.

xps_parse_resource_dictionary can now warn and return NULL when reading
an empty dictionary, rather than throwing an error.
Various bits of code are therefore updated to check for a NULL return
value.
We should cope better with multiple Resource dictionaries.
Tweak to the zip file handling when looking for parts.
Again, all from (or inspired by) Zenikos patch.

Huge pervasive change to lots of files, adding a context for exception
handling and allocation.
In time we'll move more statics into there.
Also fix some for(i = 0; i < function(...); i++) calls.

Import exception handling code from WSS, modified to fit into the
fitz world.
With this code we have 'real' fz_try/fz_catch/fz_rethrow functions,
handling a fz_except type. We therefore rename the existing fz_throw/
fz_catch/fz_rethrow to be fz_error_make/fz_error_handle/fz_error_note.
We don't actually use fz_try/fz_catch/fz_rethrow yet...

First, we add clipping rects to clipping functions. Various functions
(the ones that handle clipping) are now additionally passed a rectangle
that represents an additional bound for this clip in device space
(i.e. it has already been mapped through the current ctm).
Next, when constructing the displaylist, keep track of the bounding box
for the contents of each clip.
While writing the list, on every node we add, we add the bbox for that
node to the enclosing clips content bbox (if there is an enclosing clip).
When we pop a clip, write back to the corresponding push to update
the bbox.
This means if we get large clip regions, with only small areas used within
them, we will only do the slow blending for those small areas.
Finally, we fix a calculation in fz_bound_path which was incorrectly
accounting for mitrelimits. This was showing up in testing on page 630
of the PDF reference v1.7.

They test for NULL and make the code look nicer.

The run-together words are dead! Long live the underscores!
The postscript inspired naming convention of using all run-together
words has served us well, but it is now time for more readable code.
In this commit I have also added the sed script, rename.sed, that I used
to convert the source. Use it on your patches and application code.
