It's best to use large pixmaps for background patterns.
For instance even if it's only a 2x2 pattern, you should
create a (say) 256x256 pixmap, fill it with the pattern,
and use that to generate the background element.

It's faster to draw a big image a few times than it is
to draw a small image many times. The bigger the
"stretchy" part of the image element, the faster
things go.

I agree with you in theory but in fact we define Labelframe.border
with :

ttk::style element create Labelframe.border image $I(border) \
-border 4 \
-padding 4 \
-sticky news

to have a pretty rounded Labelframe. 'border' image is a 15x19 GIF. If
I remove 'image' property in this 'element create' command, theme will
be quick ... but the appearance is bad (dark greyed instead of white,
all buttons are squared instead of rounded...).
