This... works badly. Really. Open gimp and add some text. Now double the size of the font. Save the image and open it in image viewer, and zoom out so the text is half the size. It doesn't look the same as your original text. Rendering fonts (and even SVGs) well requires you to know the scale that you're rendering to. More pixels mean you can add more detail. If you shrink that then the additional detail is still there, getting in the way of the actually important information. Doing this properly requires that the original object renderer be part of the scaling process, and doing that on the fly with reasonable performance just isn't part of our rendering stack at the moment. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
