-    If all you want is to add an effect to an item, you should visit the
-    documentation for the specific effect to learn more about how each effect
-    can be used.
-
-    If you want to create your own custom effect, you can start by creating a
-    subclass of QGraphicsEffect (or any of the existing effects), and

-    documentation for more details. You can also get a pointer to the current
-    source by calling source().
-
-    If your effect changes, you can call update() to request a redraw. If your

+    \enum QGLContext::BindOption
+    A set of options to decide how to bind a texture using bindTexture().
+
+    \value NoBindOption Don't do anything, pass the texture straight
+    thru.
+
+    \value InvertedYBindOption Specifies that the texture should be flipped
+    over the X axis so that the texture coordinate 0,0 corresponds to
+    the top left corner. Inverting the texture implies a deep copy
+    prior to upload.
+
+    \value MipmapBindOption Specifies that bindTexture should try
+    to generate mipmaps.  If the GL implementation supports the \c
+    GL_SGIS_generate_mipmap extension, mipmaps will be automatically
+    generated for the texture. Mipmap generation is only supported for
+    the \c GL_TEXTURE_2D target.
+
+    \value PremultipliedAlphaBindOption Specifies that the image should be
+    uploaded with premultiplied alpha and does a conversion accordingly.
+
+    \value LinearFilteringBindOption Specifies that the texture filtering
+    should be set to GL_LINEAR. Default is GL_NEAREST. If mipmap is
+    also enabled, filtering will be set to GL_LINEAR_MIPMAP_LINEAR.
+
+    \value DefaultBindOption In Qt 4.5 and earlier, bindTexture()
+    would mirror the image and automatically generate mipmaps. This
+    option helps preserve this default behavior.
