annotate libinterp/corefcn/gl2ps-print.cc @ 22759:39f39eb4e476

Implement "linejoin" property (bug #48387) * configure.ac: test whether gl2psLineJoin function is available in gl2ps * graphics.in.h (line::properties): add "linejoin" property * gl-render.h (opengl_renderer::set_linejoin): new virtual method, does nothing by default. * gl-render.cc (opengl_renderer::draw_line): make use of "linejoin" property * gl-render.cc (opengl_renderer::draw_patch/suface): force "miter" line join * gl2ps-print.cc (gl2ps_renderer::set_linejoin): call gl2psLineJoin conditioned on HAVE_GL2PSLINEJOIN. * genpropdoc.m: document linejoin property.
