drawing issue of the latest reflactoring branch

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open pdf file
2. Zoom In
3. Then quickly Zoom out

What is the expected output?

after zoom in and zoom out, you will found several colored lines showing on the 
white screen or on between two different texture bitmaps.

What do you see instead?

What version of the product are you using?
lastest reflactoring branch

On what operating system?
ICS 4.0.3

What device are you using?
T959, vibrant

BTW:
It seems that every drawing circle will have lots of different calls during the 
Page, PageTree, PageTreeNode, EventDraw et.al, if we can reduce call jumps, 
maybe speed up again

"Latest" is nothing. Please specify revision.

About "calls", "jumps" and so on. Stop thinking. Start using profiler. All that 
calls and jumps are nothing comparing to bitmap blitting to canvas.

BTW, every "drawing circle" takes approx. 20 ms or less, which gives us 50+ FPS.

Странно но в ebookdroid-1.4.0-dev-r1043.apk я тоже 
заметил, что время от времени появляются 
цветные артефакты (пока находил только в 
виде цветных линий (цвета морской волны) на 
стыке страниц). Причем их появление не 
зависит от того, был ли ранее произведён 
зум или нет, но мелкий зум на стыке страниц 
может породить такую линию. Возможно это 
было и в прошлых версиях, но я не обращал 
внимания.

Радуйтесь что на стыке - они до этого внутри 
страницы появлялись в виде белых линий 
поперек картинки.

As it's hard to screenshot during zooming, so this picture is taked after zoom 
finished. and there is still colored lines there, if during zoom out, the color 
lines will be border than this.

problem improved, but the black and navy blue line still shows during zoom out 
after zoom in.

The more you zoom in and then zoom out, the more possibility you will see this 
problem

it seems this is a problem of texture bounds mismatch during zoom.

Yes. During zoom some drawing issues are present. But as far as there are no 
such issues after zoom complete I think it is a minor problem.
