Changes in SuperWaba 2.4

1. fixed images, greater than the screen, being panned.
2. added Rect.equals and Coord.equals.
3. fixed "low memory access" bug.
4. moved waba.util.Math to java.lang.Math. The VM was tweaked to find the old
waba.util.Math to keep compatibility with old versions.
5. fixed Convert.toString(d,precision). Requested by David Haysmith.
6. 6: avoid openning the combobox when its popped up and the user presses the
arrow again. Requested by David Haysmith.
7. fixed doubletostr when dealing with 99..99,99..99 -like numbers
8. fixed when adding two controls in the same location but one of them was not
visible. Requested by David Haysmith.
9. changed all bat files to call another bat to set the environment variables.
Added support for Jdk 1.4. Fixed securityexceptions occuring in Jdk 1.3.1. Fixed
problems regarding Jdk 1.4 and Retroguard. Now you can pass "noretro" as argument
to the classes/make.bat file to avoid obfuscate the VM (automaticaly done with
Jdk 1.4)
10. fixed VM to abort when tour.Tour is located in Tour (and not tour/Tour)
11. changed the target focus of waba.ui.ComboBox so parents can catch the
focus_in and focus_out event. Requested by David Haysmith.
12. In ScrollBar, make sure that at the maximum bar pos we get the maximum value
13. changed Throwable.printStackTrace to print the Exception+message instead of
nothing.
14. catched uncaught Exceptions thrown from onPaint method
15. Added ext/JTable, a good table to use with SuperWaba. Thanks to Stein Rustad
16. updated waba.util.Compression. thanks to Valentim Batista
17. now instead of return in case of bad utf, we just convert the string as is.
This fixes the case of returning an Settings.userName with accents
18. fixed ComboBox, Radio, Check and ScrollBar in Sony. Added Settings.bigFont.
19. added examples/IRChat. Thanks to Shaun O'Brien.
20. added a constant to class Window: highResPrepared. It will be used to scale
the Window when running in Sony high res devices. Since almost no user take care
of testing the program in such devices (by testing Settings.bigFont), if the
window has the highResPrepared set to false, it will scale in the setRect the
width/height to *2 and will center the Window on screen. Note: if your program
*is* prepared for sony high res, you must set this flag to true in the first line
of each Window's constructor (or after calling super). (E.G.: all SuperWaba
classes that extends window are prepared for high res, so i have setted the flag
to true in those class constructors).
21. fixed Scrollbar arrows not posting event. Thanks to Piet Jonas.
22. fixed screen corruption. Note: i think this time this is really fixed. But i
had noted that sometimes the screen still gets corrupted. Try to turn the device
off and on again; the screen should change to normal. If the screen still is
corrupted, please send me an e-mail.
23. if the postEvent before pops up another Window, we must not set the focus
back because the topMost var has changed. Requested by David Haysmith.
25. fixed str2double not recognizing negative values.
