-====== Bokeh / Depth Of Field ======
-To provide a more realistic look for you applications, Gorilla3D supplies a simple to use Bokeh (or Depth Of Field) component.
-{{ ::bokeh-example.jpg |}}
-In photography, bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens.[2][3][4]
-Bokeh has been defined as "the way the lens renders out-of-focus points of light".[5]
-Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting ("good" and "bad" bokeh, respectively).[6]
-Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions.
-Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas.[6]
-However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.

-===== Limitations =====
-Due to FMX limitations bokeh rendering have some harsh limitations.
-In FMX the cameras near and far plane is hardcoded to 1.0 - 1000.0.
-Therefore it's not possible to build a perfect implementation at the moment,
-because camera's near/far plane need to be equal to bokeh shaders near/far plane.
-===== Example =====
-<file pascal>
-procedure TForm1.CreateBokeh();
-begin
-  FBokeh := TGorillaBokeh.Create(FViewport);
-  FBokeh.AutoFocus := true;
-  FBokeh.Fstop := 1;
-  FBokeh.FrustumNearFar := PointF(10, 100);
-end;
