Let's turn off text-rendering: optimizeLegibility by default

[revelt]

Let's turn off text-rendering: optimizeLegibility by default. If somebody really wants to waste precious system resources on it, they can activate it. For the masses however, text-rendering should not have optimizeLegibility on by default.

Instead of:

p { text-rendering: optimizeLegibility; }

we should use:

p { text-rendering: optimizeSpeed; }

or even give option for:

p { text-rendering: auto; }
