* GMT PS STRUCTURE DEFINITION
*--------------------------------------------------------------------*/
/* Several parameters control the running of PSL. Some are found among
* the GMT default settings (e.g., PS_PAGE_COLOR) and these values are
* parsed by the default machinery and stored in the corresponding
* GMT->setting.ps_* parameters, e.g., PS_PAGE_COLOR is parsed and stored
* as GMT->setting.ps_page_color. All of these are used as arguments to
* PSL_beginsession, PSL_set_defaults, and PSL_beginplot which sets the
* internal PSL variables.
* A few of these parameters can also be modified via the GMT command
* line options: -P -U -X -Y -c. These options simply change the values as
* currently stored in the corresponding GMT_->setting.ps_*. Note that
* -U has a default position and justification and thus controlled by the
* MAP_LOGO_* parameters GMT->setting.ps_map_logo_* while the actual label is
* kept in the structure below as given by -U.
* Finally, there are a few PSL variables that are not initialized via
* PSL_beginsession, PSL_set_defaults, or PSL_plotbegin, such as the
* transparency or line_cap settings. These are all GMT default settings
* that are parsed directly into the PSL internal variables.
