Graphics copyArea overflow check bails out of copying pixels if there is
overflow.
The spec says ""If a portion of the source rectangle lies outside the bounds of
the component, or is obscured by another window or component, {@code copyArea}
*will be unable to copy* the associated pixels"
which suggests that we should always copy the parts inside the bounds and never
the parts outside the bounds
but it seems currently, in the case of overflow it no longer copies any pixels,
including the parts that are inside.
So, the fix clips the copyarea region to clip bounds so it will only affect
pixels within the valid bounds, and any pixels outside will be ignored.
