Thunderbird app has nice rounded tabs. rounded top edge of tab and rounder bottom. with smooth lines.
To paint such tabs, one can use AGGPas.
I want to paint such tabs in lite weight code, ATtabs, without AGGPas.
Sublime Text does it with PNG files. It has 2-3 files per left/right edge of tab.
I cannot get how Sublime does it.
a) custom width for tabs,
b) custom fore-, back- colors.
pls help with example, which paints such tabs? with PNG files or not.
