Updated image branding (issue #4444)

[goobertron]

Have created new logos, in lower case Roboto, and changed one file (an emailer) which referred to logo_caps.png. This addresses #4444.

Most of these appear unused in the code. The only two I could find being used were logo_caps.png (now logo_small.png) and powered_by_diaspora.png, which appears in the footer of the desktop version.

I'm wondering whether powered_by_diaspora in the footer wouldn't be better as text rather than an image. The image is so small that it's not easy to read. If we presented it as text in light grey, it would probably look better and also scale better.

But do we even need 'powered by diaspora*' there?

logo_white4x.png is one which I may use in a redesigned default.html

For some reason in all the graphics the letter d and i are sitting a pixel or 2 higher than "aspora"

Also, I think the edges of these new ones are far to hard/sharp.

Hi Ruxton, thanks for your comments. Point 1, that's very odd. It shouldn't be the case as they were typed on a line. I wonder whether it's a Roboto thing, the d and i not coming quite as low on the line as the other letters in the word?

Point 2, I agree. I was unable to find a way to soften the edges without including a background into the image so there is some blending of the edges. The smallest images particularly suffer from this. In the end I did include a background with powered_by_diaspora.png because it looked awful otherwise.

It may need either a rethink on how logos are presented in the app, or someone with greater skills with graphics than I!

Just a thought: now that Roboto is included in the diaspora installation, do we actually need to provide graphics for the word 'diaspora*' at all? Could we use text instead of images?

[goobertron]

One thing I can do is to blur the edges of the type before rasterising. This helps, but still doesn't look great, in my opinion.

Can anyone think of downsides of not using images at all for branding that is strictly based on a font? I cannot, except maybe for older browsers - but we pretty much don't support old browsers :)

I'll merge this for now, thank you @goobertron! We can always further reduce the image usage at some later point.
