KLF_EXPORT void klfDrawGlowedImage	(	QPainter *	painter,
		const QImage &	foreground,
		const QColor &	glow_color = `QColor(128, 255, 128, 8)`,
		int	radius = `4`,
		bool	also_draw_image = `true`
	)

Draws the given image with a glow effect.

Draws a glow effect for image foreground by extracting the alpha channel, and creating fills an image of color glow_color with the same alpha channel. The image is then drawn at all points (x,y) around (0,0) such that |(x,y)-(0,0)| < r, effectively overlapping the glow image with itself creating a blur effect.

The resulting graphics are painted using the painter painter, at the reference position (0,0). If you want your image drawn at another position, use QPainter::translate().

If also_draw_image is TRUE, then the image itself is also drawn on top of the glow effect.

KLF_EXPORT void klfHideWindows ( )

Todo:: THIS IS A WORKAROUND to avoid "hiding" the system tray icon when hiding all windows (which is of course not what we want!). This also has the undesirable effect of not hiding all windows which have the x11-bypass-window-manager flag on. TODO: write some more intelligent code.

QImage klfImageScaled	(	const QImage &	source,
		const QSize &	newSize
	)

Scale image, preserve aspect ratio and meta-information.

Calls QImage::scaled(), with instruction to keep aspect ratio, to scale to new size, with a smooth (not fast) transformation.

Then copies the original image's meta-information to the returned image with QImage::setText().
