Bug 127070 SVG small font is always antialiased
SVG uses glyphs to render fonts, which cause small fonts to be always anti-aliased (making them slightly blurry), and "low quality SVG" (no antialiasing) text to be almost unreadable. As a more minor side-effect this also causes the SVG source to be not very readable and large in size.
