fix(draw): render hex and rgb encoded color markers 

Until now we did not properly sanitize the IDs we create for colored
markers. This would make the marker retrival fail with fill and
stroke colors encoded in hex and rgb(a, b, c) form.

This commit improves the situation by removing forbidden chars from
the marker ID.

Closes #981
