Themeroller does not optimise outputted images

[strikernl]

I'm not sure if this is even really an issue, just something I noticed (it may not be themeroller centric either):

The PNGs outputted by themeroller, for example the icons, are not optimised, for example:

https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.3/themes/smoothness/images/ui-icons_222222_256x240.png

Gives the following in Google Pagespeed Insights:

Consider Fixing:
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 2.5KiB (37% reduction).
Losslessly compressing https://ajax.googleapis.com/…hness/images/ui-icons_222222_256x240.png could save 2.5KiB (37% reduction).

No big deal, just thought I'd mention it ;)
