爱可视605看PDF程式源代码, 基于APDF

- The document lasgen.pdf isn't rendered correctly when the zoom
  is too small. This started to happen after the move to the poppler-dev
  code-base. The document is made up from scanned pages.

- The fontconfig presentation handouts arent rendered correctly either. This
  also started to happen after the changes to the poppler-dev code-base.

- The spinbar doesn't look to good on the device.

- The disable pictures feature is disabled ATM. Do we actually
  need it? Would it make sense to check for available memory
  and don't display images which are bigger than a certain size?
  If we enable the feature again it should be done
  through gfx.h again because it's a xpdf interna.

- What about chinese/hebrew fonts? This must at least be tested.
  Spinbar and Menu are the only places to look for.

- When running on the device sometimes there were completly white pages.
  Can't reproduce ATM.

- When moving fast though pages the sidemenu is sometimes not updated fast
  enough.

- merge the archos specific stuff done for the old poppler code-base into the new code-base

- Check if the focus can be kept more accurate while zooming

- Possible optimisation: have the graphics inside the document with the right dpi
  so they don't need to be resized.

- The "fit to page" and "fit to width" modes for the OSDEV.pdf don't work correctly. The
  bitmaps created are too small. The strange thing is that the values for "fit to width"
  are correct, other A4 documents have the same values but cover the screen correctly.
  Can also be reproduced with the PDF-Reference manual. KPDF also uses the 72dpi for
  calculating "fit to width/page". cda.pdf shows also interesting behaviour.

- It would be nice to have one hierarchie level less under opt

Done:
- The green startup screen if the QWS Server must somehow be hidden from the user.

- Test the translation process before hand. Linguist is available.

- On the device there are minor graphic glitches around the slider cursor. Was fixed by
  the QTE alpha workaround.

- The text inside the spinbar and the menu panel has some
  "noise" around it. This does not happen inside the simulator.

- For "fit to width" there shouldn't be a border at the left/right, only at 
  top/bottom.

- Slider selection is a little bit flaky when there are only a few items.

- Update the zoom in/out bitmaps with the more recent AVOS version.

- We need to have different bitmaps for different screen resolutions! Don't forget
  to handle resizeEvent for the pdfWidget. The Slider seems to have the same size
  for tv and wqvga in AVOS.

- ATM the gotopage widget has a random(?) size. Implement proper size hints. The slider range
  must be dynamically adjusted to the desktop dimensions.

 - There should be more spacing a the left, right side of the menu.

- The selection for the last menu item is one pixel to low (it touches the border...).

- Check if left/right are really a good thing with links and scrolling!
  We should only choose a new link if we find one more to the left/right!

- Allways scroll if possible even when moving the link cursor. This will make toc with
  plenty of links faster to navigate.

- The bluestreak SystemGuide documents had really strange links. Scrolling through
  those links didn't work properly. My guess there are several links at exactly the
  same location. Links are actually selected but the cursor isn't seen?!
  Explanation: there are allways two links at the same location. The green (active)
  cursor is painted over by the inactive marker (red) so the cursor isn't seen.
  I don't think i can do anything against this.

- Links realized with PageRefs weren't followed.

- Test different resolutions for the pdf reader! There is some hardcoded stuff.

- Goto Page should adjust the scrollview so the top of the document is visible.

- Add mouse support for the gotoPage widget.

- If the document has exactly the right dpi (manual) the first zoom mode is a non-op.
  The special case is: fit to page dpi == fit to width dpi.

- When running in fitToX mode we must recalc the dpi for every new page because page
  size and orientation can change between pages.

- The static versions of fontconfig and expat still end up somehow on the target. Not big but
  ugly!

- Fix the e2fsprog makefile. It will install more than needed onto the target. It's only
  a few kb, but...

- The user interface should automatically disappear after not using
  it for some time.

- Clicking outside the sidemenu panel should close the panel.

- Mouse events inside the pdfWidget should prevent the ui from hidding.

- Check if the patent critical bytecode interpreter is disabled in freetype!

- The selection inside the side menu is sometimes a little bit off. The further down the
  more off.

- Adjust the selection cursor for TV mode.
