Because inline strings have to be copied (to escape '$') the local buffer
can be exhaused. The code didn't check for this. The buffer is increased
to handle filenames plus some extra chars but truncates to avoid overflow.
If you have longer strings please pass them via $t tag, in which case
put_line() imposes no additional length-limitation.

This logic is moved into apps (put_line()) which can better handle line
decorations with respect to scrolling, mulitline and other complications.
Firmware doesn't need this. The remaining drawing function know only one style,
that is foreground on background/backdrop (changing drawmode is still supported).

This function is a fully-fletched, high-level pixel-based line printer, that
combines functionality of several firmware and list functions. It can
draw spacing, icons and text in a single call, in any order and each multiple
times. It can also apply line decorations at the same time.
It features printf-like semantics by accepting a format string that contain
format tags as well as inline text.
It's accessible directly, but also through the multi-screen api for plugins.
