Description
Sends a PM_SET_SIZE message to the presentation layer through its presentation proxy.
DoSetSize does not set the specified dimensions (ANewWidth, ANewHeight) directly. Instead, DoSetSize requests a recommended size to the presentation layer based on the specified dimensions, and sends that recommended size within the message.
DoSetSize returns True if the new (recommended) dimensions match the current dimensions, or False otherwise.
For details about the circumstances that trigger this procedure, see TStyledControl.DoSetSize.
