TDrawing or a descendant is used to draw a graphical image for a control at runtime and context sensitive (not necessarily static). Because such drawing is not dependent on a special graphical resolution (like raster graphic images), large images don't require large memory, and small images can be stretched without a loss of quality (resolution).
