Yes, but then it will be a TButtonPlus. A normal TButton is the normal
button of the theme.

Correct. But if you want a 'red' button, then you want a custom drawn
button, not a TButton.
If 'red' buttons are needed that often, then we should add a
TCustomDrawnButton (or whatever name fits) with properties like Color,
Frame, BorderWidth, TextAlignment, WordWrap, ... .
This has five advantages:
- the button will really look the same under all platforms
- less code in LCL interfaces
- better for smartlinking
- more flexibility
- cleaner design (themed and non themed controls)

It should. If not, you found a bug.

Can you give more details?
