[webkit-dev] Problems porting layout tests to linux

[Darin Adler]

To improve the situation, I'd like to see some of the following happen:

     1) Reorganize the tests so that tests that should work across  
all platforms are separate from ones that might need different  
results per platform. (Perhaps we could rationalize the organization  
and naming of tests in some other ways as well.)

     2) Change more tests to use dumpAsText as a way of making them  
platform-independent.

     3) Come up with some techniques to make tests independent of  
font widths to make them platform-independent; for example, perhaps  
we can create a font with widths that are consistent on all platforms  
and use it for most tests.

     4) Consider alternate dumping formats that would include what's  
relevant to check if a test succeeded that don't dump the entire  
layout and position of each element -- something in between "dump as  
text" and "dump render tree".

Also, I think the DumpRenderTree tool is going to need a rename  
eventually. That was a good name for the original tool back when I  
first wrote it and it was only about render trees, but now it's more  
like "test engine" or something along those lines. Similarly, I think  
the LayoutTests directory might need a rename for similar reasons.
