Trying to grab a screenshot of a MAC application (bug 44176), we hit a snag with
Text widgets which dont paint to the GC. The problem seems to be that Text
widgets are painting directly to the screen even when asked to paint to a GC,
specifically in Text's api:
-------------------------------------------
void drawWidget (int control, int damageRgn, int visibleRgn, int theEvent) {
	OS.TXNDraw (txnObject, 0);
	super.drawWidget (control, damageRgn, visibleRgn, theEvent);
}
-------------------------------------------

Looking at the API of OS.TXNDraw() on Apple's website at
http://developer.apple.com/documentation/Carbon/Reference/Multilingual_Text_Engine/mlte_refchap/chapter_1.2_section_19.html#//apple_ref/doc/uid/TP30000069-DontLinkChapterID_2-F12521
It says that specifying NULL or 0 in the second argument paints to the screen
instead of the buffer. Was wondering if this was what was causing the text to
not paint. An illustration of the problem can be found here:
https://bugs.eclipse.org/bugs/attachment.cgi?id=26475

The code used to capture the image:
--------------------------------------------
protected Image getImageOfControl(Control control){
	Image image = new Image(control.getDisplay(), control.getBounds());
	GC gc = new GC(control);
	gc.copyArea(image, 0, 0);
	gc.dispose();
	return image;
}
