cursor: Switch to BreezeX Black

I still prefer Breeze-Obsidian, but the reality is that it's unsupported
and nobody even seems to have the source any more :(

Allow `dpi` script to scale cursor relative to display scale according
to a fixed "standard" size, which for BreezeX is around 28px to closely
match the scale of the Breeze-Obsidian 16px.
