The IDE can only display the controls it uses itself. For every other 
control, it will display a frame with the control icon inside (it does 
not know how to draw the control).

Otherwise, you can define the "_DrawWith" constant to tell the IDE which 
standard control it can use instead to draw the new control.

I don't want the IDE to dynamically load components just to draw them, 
because it's a security risk, and a potential source of errors.

No. You can do that with library projects, not component projects.

See components like what device drivers are for the Linux kernel.

If your control is well written, we can put it in the 'gb.form' 
component. That way, the IDE, as it uses that component, will be able to 
draw it.
