This commit calculates the rectangle that will be drawn
correctly. Now the mapped rectangle is calculated wrong,
but it gets the text of the document and copies it to
the clipboard.
This patch checks while opening the pdf document
if it is reasonable to activate the goto label mode:
Sometimes all labels match their page number and then
the label goto mode will slow the navigation down.
This commit is build on the idea of Renato Florentino to be able to
correct the page offset that some documents have. His patch, where
most of the code has been adapted to this commit ( thanks! ), made
it able to correct the current page and automatically calculate the
correct page offset. Now this patch will introduce a third mode to
the bcmd_goto command: You are now able to set the page directly,
calculate it over the offset or search the labels for it.
The page labels are now used in the buffered command bcmd_goto, so
if this option is enabled and you try to reach page number 20, zathura
first seraches for a label named like that and moves to that page instead
of moving to page 20 in the document.
With this commit it is possible to show and use the labels of a page,
which makes it possible to use a page offset. E.g.: Sometimes the page
numbers written on the page in the document differ from the order in the
file, which can be annoying by e.g. trying to go to the page number >20<
that is instead page number >24< in the document.
This patch provides the functionality to browse through the index
via the keyboard hence the mouse is not needed anymore. The original
author of this patch is int3 <jezreel@gmail.com>, in addition there
has been introduced a fix solving problems with named destinations.
