annotate libinterp/corefcn/gl2ps-renderer.h @ 20090:438485f6a479
Honor the axes stack order in gl2ps outputs (bug #44765)
* gl2ps-renderer.h (glps_renderer::draw_axes): new method to init a new sorting
tree in gl2ps each time a new axes is drawn before calling
opengl_renderer::draw_axes.
* gl-render.cc (opengl_renderer::draw_axes_planes): don't draw xz and yz planes
when in 2D mode.
