[lazarus] Delphi incompatibilities in TForm

[Giuliano Colla]

Trying to convert to Lazarus Delphi projects, I stumbled in quite a 
number of incompatibilities. Let's start with TForm.

1) TForm.Color property sicks stubbornly to clBtnFace, whatever you do. 
Setting a different Color triggers a repaint, but the form is painted 
with the default color. What is weird is that if you put a component 
such as a Panel on the form and set its ParentColor true, then the 
component is painted on the Form.Color you set, while the form below 
doesn't change. See attached images. Panel1.Parent Color is set to true, 
and an OnClick event sets Form1.Color to clLime.

2) Delphi Form has a Bitmap property which allows to set a background 
image on the form, while Lazarus does not.

Of course there are workarounds, using OnPaint events, but this isn't 
pretty, because the form is first painted as lazarus believes right, and 
then repainted as I want.

Are those design choices, or bugs?
