<p>\param renderer The renderer for which resolution should be set.
\param w The width of the logical resolution
\param h The height of the logical resolution</p>
<p>This function uses the viewport and scaling functionality to allow a fixed logical
resolution for rendering, regardless of the actual output resolution. If the actual
output resolution doesn't have the same aspect ratio the output rendering will be
centered within the output display.</p>
<p>If the output display is a window, mouse events in the window will be filtered
and scaled so they seem to arrive within the logical resolution.</p>
<p>\note If this function results in scaling or subpixel drawing by the
rendering backend, it will be handled using the appropriate
quality hints.</p>
