currently, the text coordinate always is at the upper left of the text bounding box - obviously resulting in top-left aligned text.

For some use cases (especially when displaying numbers), right alignment would be a nice option to have.

For this, we could add a new alignment setting (similar to the way that colors are set) like set_text_align(mode). An open question here is whether the vertical alignment is also necessary or if left, center, right are enough.

Tcl/Tk uses compass directions for this (see https://www.tcl.tk/man/tcl8.4/TkCmd/options.htm#M-anchor): n, ne, e, se, s, sw, w, nw, center ... that would be an option as well, but not sure if needed and if that would easily be adaptable for purr data and plugdata?
