(change_marker): Add new function to change size of marker. * scripts/plot/draw/private/__scatter__.m: Use new graphics object if the current graphics toolkit is not "gnuplot". Move the fall back code for gnuplot to a new function. * scripts/plot/draw/private/__gnuplot_scatter__.m: New function with the code moved from __scatter__.m. * doc/interpreter/genpropdoc.m: Add documentation for scatter properties. * doc/interpreter/graphics_properties.mk, module.mk: Add build rules for documentation of scatter properties. * doc/interpreter/plot.txi: Add reference to scatter properties. Remove outdated section for "Scatter Group". * doc/interpreter/octave.texi: Add new section and delete removed section from table of contents. * scatter.m, scatter3.m: Add cross reference to scatter properties in docstring. * struct2hdl.m: Support loading scatter objects.
