[ubuntu-art] Tangerine Icon Request: Check-mark and Red-X

[Mikkel Kamstrup Erlandsen]

This is espicially obvious in Synaptic... The green Apply check-mark
icon is heavily pixelized - as is the red X in Cancel buttons. This just
looks totally out of place in between otherwise antialised icons.

Since I've long ago realized that I suck at making icons, I just hope
that some one could do my eyes a favor ;-P

Cheers,
Mikkel
