Fix Z-order stacking of patches and axes grid lines (bug #40722).
* gl-render.h (set_polygon_offset): Change function prototype for offset
argument to float.
* gl-render.cc (set_polygon_offset): Change offset argument to type float.
Now matches OpenGL prototype for glPolygonOffset.
* gl-render.cc (patch_tesselator::patch_tesselator): Change constructor
variable idx to a float, from int.
* gl-render.cc (patch_tesselator::begin): Pass index directly to
set_polygon_offset.
* gl-render.cc (opengl_renderer::draw_patch): Call patch_tesselator with index
of 1.0 for filled portion of patch to push it down below outline of patch.
* patch.m: For 2-D patches, set zlim to [-1,1] so that axes 'layer' property
works.
