get-view-size

Returns the visible area into which the buffer is currently being displayed (according to the buffer's administrator).

The result is only valid when the buffer is viewed (see Basic Organization).

• (send a-wx:media-buffer get-view-size w h) -> void
      w : boxed inexact real or null
      h : boxed inexact real or null

  The w box is filled with the visible area width, unless w is null. The h box is filled with the visible area height, unless h is null.
