8e4516b824 add regional zoom mode in pdf/djvu page 
In regional zoom mode double tap will zoom to the tapped
region(paragraph or column, etc., detected optically via libk2pdfopt).
As the first demo, this feature is only turned on in flipping mode by
tapping the top-left corner of the screen. Eventually we may incorporate
this feature in "free" zoom mode.

71cb2d3f93 fix looking up wrong word in reflowed page 
that has a text layer underneath.

For multi-column page reflowing usually fits individual column to
page width and no finner word boxes are available to map reflowed
word box onto native word box. Now the relative position of a reflowed
word center is calculated as portion of the width and height of a larger
block it belongs. This relative position is also considered in
reflow-to-native position transform so that dictionary lookup now works
on multi-column pages in reflowing mode.

This should fix #376.

2154e7e852 Further refactoring 
This should finish the work to make all globals to local variables.
That allows LuaJIT to properly compile things by interning the
references to the relevant parts (rather than looking up globals
all the time which stops a trace).

2cd5a083ae fix getAutoBBox failed bug 
If getAutoBBox is fed with a blank page the returned bbox will be
much smaller than the native page dimensions. The problem is that
in zoom to 'content*' mode document renderer will try to render
the whole page at a zoom level that can cover the screen with the
bbox region of the page. That's if the blank page size is 3000*4000
and the returned autobbox is 300*400, the screen size is 600*800,
then the page will be rendered in 3000*(600/300)*4000*(800/400)
which is so large that the cache manager will not accept.

This patch just check if the returned autobbox is considerablely
much smaller than the native page dimensions. If so it will return
the manual bbox.

This patch should fix #293. And it's tested with the case provided
by @Markismus in #291.

9cb9999865 semi-automatic bbox finding 
Semi-automatic cropping is implemented with a initial
manual cropping that exclude the obvious decorating line or
the spine part in scanned books and then an automatic cropping
ie. background/foreground pixel detection restricted within
the manual cropping area.
This PR is a candidate for the solution of issue #141.
