Description:
Hi,

I noticed in the latest ubuntu-artwork, titlebar buttons (maximize,
close...) are a bit wider than tall. Like in Vista, though less
elongated.

I propose to make them much wider. This would enable the titlebar height
(and area) to be decreased, thus sparing screen space, while keeping the
same clickable area for the buttons.

I tested this and it works like a charm: edit /usr/share/themes/Human/metacity-1/metacity-theme-1.xml
and change "aspect_ratio" from 0.9 to 0.3 (in both places).

This works well for small titlebars, but not for thick titlebars. To
solve this, the button width could be made to depend on the titlebar
height. I.e. the button AREA should be a constant, and the width should
be computer with the formula

current_button_width = 
constant_area / current_titlebar_height
