So, why dont we have "Fast Width 1 Graphic" to "Yes" as a factory default ? One reason is that it can break applications (we've already seen one) Another is that later this year MIT will be releasing an X Test Suite that checks pixelization (i.e. which dots get drawn). We've already seen many customers who plan to run the test suite to verify that vendors are shipping compliant products. One of the reasons why engineering has been opposed to making fast-width-1-graphics on by default is that the test suites will immediately fail and NCD will probably receive negative press. While we recognize that this might not be the simplest approach in the short run for those of you in Sales, we believe it will pay off in the longer term. Also, one have to be carefull that as the difference in drawing quality is not quite obvious, Depends on your application. Some (admittedly few at this point) applications use the pixelization rules to allow them to lay out graphics on the screen in exact positions; width-0 lines will break that and can leave spots on the screen (technical term for which is "turds" :-). It may be possible that sometime we get compared to an Xserver which silently draws width 1 graphics as width 0 for speed optimization (apparently some PC Xservers do that). Such servers will fail the test suites and I'm sure you'll let the customers know that! Jim Fulton said "My personal opinion is that this, and other features which are useful but break compliance, should be explicitly highlighted in the installation and configuration screens. That way, customers can find out about them and not be tripped up by them being set one way or the other."
