The core library doesn't know where a document comes from, since we can
open it as a stream, etc. Let the viewer handle relative file URLs.
|
|
Also zoom to fit the window.
|
|
This uses an undocumented Rotate property of annotations, which is also
used by Adobe.

This option is exposed as the -D flag to mutool clean.
Allow saving a document without encryption.
The next step is to allow saving a document with new encryption, but this
may require a fair amount of rejigging since the PDF write code to keep
separate doc->crypt objects for decryption and encryption.

Also save history when glut closes the window or otherwise exits the
main loop.
|
|
Use MuJS to parse/write JSON object.
|

|
|
When clicking a text/choice/signature field, pop up a dialog to fill in
the value.
Hide widget annotations in annotation editor.

The macro is only set when building the pkcs7-helper library, so cannot
be used by client code. Build stub functions when compiling the
pkcs7-openssl helper library without libcrypto.

The intent is for a user to iterate over the annotations on a page calling
pdf_update_annot for each one. If this function returns true, then the
annotation has changed since the last time it was called, and the user
needs to re-render.
pdf_update_page is a simple loop over the annotations on a page, for use
if you only care about page level granularity.
Users should no longer look at or change the pdf_annot.has_new_ap field.

All the "Sign" button does for now is recreate the appearance stream.

Create a matrix that transforms a page with resolution and rotation,
and grid fits the resulting bounding box.

Several things irk me about passing values as const pointers:
* They can be NULL, which is not a valid value.
* They require explicit temporary variables for storage.
* They don't compose easily in a legible manner, requiring
weird pointer passing semantics where the variable being assigned
is hidden as an argument in the innermost function call.
* We can't change the value through the pointer, requiring yet more
local variables to hold copies of the input value.
In the device interface where we pass a matrix to a function, we often
find ourselves making a local copy of the matrix so we can concatenate
other transforms to it. This copying is a lot of unnecessary busywork
that I hope to eventually avoid by laying the groundwork with this
commit.
This is a rather large API change, so I apologize for the inconvenience,
but I hope the end result and gain in legibility will be worth the pain.

Updates the input point coordinates, and also returns a quad with
appropriate UI handles.
|

Since the function no longer returns ownership of the string, use the
common naming convention.
|
|
|

Removes the need to alloc/free text strings in the API, allowing
for simple functions like pdf_dict_get_text_string.

Handle the logic immediately, but put the drawing commands into a
display list that is invoked after the rest of the UI is drawn.
|
|
Also increase the max resolution in the zoom list.
