rendering.;

#X text 22 161 - The "window" checkbox sends [create( and [destroy(
to [gemwin];

control the rendering.;
#X text 23 341 Each checkbox will turn green when enabled. When the
whole object turns green , that means everything is ready to display
data in the gemwin.;

it will not be generated. Render chains generally end with an shape
