annotate libinterp/corefcn/gl-render.cc @ 22362:f3ce0015dd42

Draw tick marks in appropriate axes color (OpenGL renderers). * gl-render.cc (draw_axes_x_grid, draw_axes_y_grid, draw_axes_z_grid): Move drawing of minor grid and major grid to the beginning of function. Next, set color based on axes property and then add tick marks and text.
