Fraser #2 states this, but it won't be enough. In fact, it may be useful
only for programs with a single SciObj, such as SciTE.

For each buffer (each SciObj), I guarantee...

Since a plugin may not need to set [all of] it's markers for each file,
and we may even have 0 buffers open, a guint map seems required, and I
was probably wrong to suggest AVAILABLE. Can't query/define Scintilla
markers without at least 1 SciObj...

utils_ui_get_marker(), utils_ui_free_marker().

Shoudn't the plugin handle this? It may reduce the number of markers
used, work without them if non-critical, or do something else.

Ten markers? Wow, that's heavy. Different colors or what?
