[Gnash] test cases

[Rob Savoye]

I just created a gnash/testsuite/actionscript.all directory for 
ActionScript test cases. Hopefully these can all be generated using Ming 
or other free tools. My thought for test cases structure is to have a 
single file exercise a single ActionScript class. Ideally all of the 
methods can be exercised from within this test file.

For now we'll have to run each test case by hand with the standalone 
player, and determine the test outcome by human eye. Once I get a 
chance, I'll wrap the test cases so they execute under DejaGnu in an 
automated fashion. That'll take some work, since ultimately it'll be 
necessary to grab the window and examine it's contents. My current 
experiment does two things. One, it just analyzes the debug output from 
the standalone playing using the -vp and -va options. This is crude, but 
better than nothing. For the next step, I'm experimenting with using 
autotrace to render the window bitmap to a DXF file, which I can then 
walk through and see if all the proper graphic elements are the right 
size, and in the right place.

As neither of these can test events, like clicking a mouse on a rendered 
button, last I'll see about using a headless X display or X remote 
control program.

At this point though, it'll be good to start collecting and creating 
test cases, since it'll still help make sure Gnash is operating correctly.

For whole movies, I'm sticking some for testing in the 
gnash/testsuite/movies.all directory. These are probably too complex for 
automated testing, but all illustrate something Gnash is or isn't 
parsing and rendering correctly. Plus they'll make useful demos.
