Reorganize "concept" pages in QtQuick docs

This removes concepts/topic.qdoc and move this content into individual
concept topic pages under individual directories for each concept to
avoid having a really long "concepts" index page.

This change also:
- Moves components.qdoc ("Defining reusable components") into the
 appdevguide/ since it's not specific to QtQuick features - it's more
 about how to use a QtQml feature to build QML apps.
- Moves the part of qtqml/doc/src/cppintegration/data.qdoc that
 discusses how to use C++ models with QtQuick views into
 quick/doc/src/concepts/modelviewsdata/data-cppmodels.qdoc.

+\title Important Concepts In Qt Quick - Graphical Effects
+\brief Overview of graphical effects concepts
+
+\section1 Graphical Effects and Particles
+
+Visually appealing user-interfaces are more engaging than lacklustre ones.
+That said, the designer must bear in mind that visual effects simply provide
+a useful way to subtlely communicate to the user (for example, which visual
+item is active, or how focus is being transferred).  Over-use of visual
+effects can actually detract from the user-experience.
+
+\section1 Visual Transformation
+
+Visual objects can be transformed.  For example, they can be scaled or rotated.
+These sort of transformations can provide hints about focus or selection, and
+can provide intuitive hints about what events are occurring in an application.
+
+For information about visual transformations to visual objects, see the
+page titled \l{qtquick-effects-transformations.html}
+{Qt Quick Transformation Types}.
+
+\section1 Shader Effects
+
+Shader effects allow the full, raw power of a graphics processing unit to be
+utilized directly via vertex and pixel shaders.  Using too many shader effects
+can result in increased power usage and sometimes slow performance, but if
+used sparingly and carefully, a shader can allow complex and visually appealing
+effects to be applied to a visual object (for example, ripples in water).
+
+For information about shader programs and shader effects, see the page
+titled \l{qtquick-effects-shaders.html}
+{Qt Quick Shader Effects}.
+
+\section1 Particles
+
+A particle system allows explosions, fireworks, smoke, fog and wind effects to
+be simulated and displayed to the user.  Qt Quick provides a particle system
+which allows these sort of complex, 2D simulations to be performed, including
+support for environmental effects like gravity and turbulence.
+Particles are most commonly used to add subtle and visually appealing effects
+to currently selected items in lists or in activity notifiers, and in games.
+
+For information about particles, see the documentation about the
+\l{qtquick-effects-particles.html}{Qt Quick Particle System}.
+
+\section1 Sprites
+
+A sprite is an animated image made up of frames.  Sprites are commonly found
+in games.  Qt Quick provides a visual type to display sprites, as well as a
+complex, stochastic, frame-transition controller for more complex applications
+which use sprites extensively (such as games).
+
+For information about sprite animations, see the page titled
+\l{qtquick-effects-sprites.html}{Sprite Animations}.
