Messaging Menu received optimized envelope icon (Ubuntu 12.10)

Unity offers, along with the Dash and the launcher, a top bar/panel, from where indicators can be accessed via their (default) monochrome icons.

Weeks ago, a refreshed version of the Messaging Menu arrived in Ubuntu 12.10, bringing specific names for contained entries, Empathy status-aware panel icon (the envelop gains on its "surface" icons representing statuses, such as Away, Available, etc), yet the Messaging Menu's Indicator (Indicator Messages) was expressed with an improper icon size, size rendering the envelope both blurry and with a decreased size (as compared to a "standard" size used by other Unity panel icons).

The latest updates fix the faulty icon rendering, by delivering a proper optimized Messaging Menu's indicator icon, consequently, the icon features a crisp clear look, furthermore, the size is now aligned with the other icons (situated on the panel).
