Members at a glance

`WatermarkProvider`	Initializes a new instance of the `WatermarkProvider` class.
`ShouldRenderWatermarkImage`	Whether the image part of the watermark is drawn. Text-only watermarks leave it false.
`WatermarkImage`	The image drawn as the watermark, or null for a text-only watermark.
`WatermarkImageSize`	The size the watermark image is drawn at.
`WatermarkText`	The text drawn as the watermark while the control is empty.
`OnSizeChanged`	Raises the SizeChanged event. The provider overrides it because its two children were positioned only when the watermark image changed, so a text-only watermark - the ordinary case - was laid out once at construction and never again.
