Will Opera have its own font rendering with excellent anti-aliasing?

Testing the experimental build of the Opera with @ font-face support, I felt something was wrong - the usual fonts in it look unusual. Is this a proprietary anti-aliasing system or some particular use of ClearType? The first option is plausible for the following reasons:

1. Administrator privileges are needed to install fonts into the system - the proprietary font rendering system solves this problem, and on all systems at once.
2. I know about Mac, I don’t know about Linux, about Windows I can see that ClearType is terrible. Since Opera can draw fonts, why shouldn't she smooth them out herself?
3. Fonts are not displayed the same on all systems.
4. Not PC devices that Opera targets, as I understand it, do not have anti-aliasing at all

To test the guesses, I will disable system anti-aliasing, see how the fonts look without it in Opera 9.51, IE6, and the assembly of opera_wingogi_acid3 and with it. When switching browsers rebooted.

As a bonus, see how a large page looks like with ClearType in Opera 9.51 and with its own anti-aliasing system in opera_wingogi_acid3 . Reading the text and surfing is a pleasure!

It's funny that the assembly was ignored by the community for both support for @ font-face, and for the presence of its own rendering and anti-aliasing. And the reason for this can only be called scant information in the release
