[Lazarus] mod to make Anchor Docking Grab Handles have a more subtle look

[Graeme Geldenhuys]

Hi,

I've created a patch to make the Docking Grab Handles (of Anchor Docking 
package) to have a more subtle look. The original look was too 
distracting for my personal taste. I like it to blend in better with the 
main form.

Mantis report with patch:

I tried to keep theming in mind. I made the background of the handles 
clForm. This could probably be tweaked to a difference color, if you 
want the handles to stand out more.


As I mentioned in the Mantis report. If this is not the look that the 
Lazarus team is going for, then please disregard my patch.


Regards,
