+#X text 469 288 gemhead takes an argument to determine when it receives
+the render command. The default value is 50 The lower the value is
+\, the sooner the gemhead will receive the rendering command (a value
+of 1 is the lowest possible value (see below)). This value becomes
+important when you are doing alpha blending and for certain objects
+(such as light).;
+#X text 469 495 example: "1" before "50" before "-10" before "-23"
+;
+#X text 470 416 the rendering-order value can also be negative. Negative
+numbered [gemhead]s will be rendered AFTER all positive [gemhead]s.
+Note \, that Higher values (-3) will be rendered BEFORE lower values
+(-10). [gemhead]s with negative numbers will NOT be affected by view-point
+changes !!!;
