+ <description summary="Protocol for requesting fractional surface scales">
+ This protocol allows a compositor to suggest for surfaces to render at
+ fractional scales.
+
+ A client can submit scaled content by utilizing wp_viewport. This is done by
+ creating a wp_viewport object for the surface and setting the destination
+ rectangle to the surface size before the scale factor is applied.
+
+ The buffer size is calculated by multiplying the surface size by the
+ intended scale.
+
+ The wl_surface buffer scale should remain set to 1.
+
+ If a surface has a surface-local size of 100 px by 50 px and wishes to
+ submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
+ be used and the wp_viewport destination rectangle should be 100 px by 50 px.
+
+ For toplevel surfaces, the size is rounded halfway away from zero. The
+ rounding algorithm for subsurface position and size is not defined.
