* hwhw/master:
fix a Lua 5.0 syntax that was deprecated in 5.1
separate DC out of pdf.c and djvu.c (cleanup)
removed obsolete page rotation handling, closes#70
allow easier customization of toolchain for libdjvu
fix: remove page number checking in displaying TOC
fix: handle LPGBCK and LPGFWD in selectmenu
Former showTOC() method checks the page number in each
entry and only display entry whose page number is greater
than the previous one. However, I think this is too
"clever", we should better leave the TOC untouched to keep
consistent with other pdf readers.
Fixed page caching. Cache strategy is the following:
prio 1: cache/render requested area
prio 2: cache/render as much of the current page as possible
prio 3: cache/render full page
prio 4: render next page
This is still a bit buggy when in fit-to-content mode.
we allow for bigger render buffers, so the cache now returns
the ID (hash) of the relevant cashed tile PLUS offsets into that
tile, pointing to the coordinates where the requested frame
has its origin.
It's not that simple since ZOOM_FIT_TO_CONTENT_HALF_WIDTH also
needs bounding boxes, and this seems like over-optimization
which seems to be bug infested especially because it deals
with negative numbers so code just *looks* wrong
* Since fontchooser is replaced by selectmenu, it
is no longer needed. So I rewrite it into font.lua
module which can cache faces that shared among all
UIs.
* add progressBar method in graphics.lua to draw
reading progress.
* add reading progress information in reading menu.
It is just a demo. Should be clean up in next release
when the real reading menu is out. :)
Now you get a instance rotate :) With only one bug.
I have to restore to previous rotation state of the
native system after exists. Because the native system
does poll the new rotation state that changed by ioctl.
Currently, I don't know how to force the native system
to detect the changes.
* move rotation mode to global variable, now check rotation
with Screen.cur_rotation_mode
* move screenRotate to screen module so other UIs can use it.
