line width units, on-screen and export visibility. So now we can use that to modify the default styles, or to create custom styles. Also add code to draw fat lines, with round endcaps, since gl doesn't do that. Next we need some user interface to assign styles to entities, and to make all the export file formats support the style attributes. [git-p4: depot-paths = "//depot/solvespace/": change = 2029]
