   All the functions that returns class pointers create new object, and the
   responsability of those is given to the callee.

   The only exception is \link Poppler::Page::transition() Page::transition()\endlink.

   \section document-loading Loading

   To get a Document, you have to load it via the load() & loadFromData()
   functions.

   In all the functions that have passwords as arguments, they \b must be Latin1
   encoded. If you have a password that is a UTF-8 string, you need to use
   QString::toLatin1() (or similar) to convert the password first.
   If you have a UTF-8 character array, consider converting it to a QString first
   (QString::fromUtf8(), or similar) before converting to Latin1 encoding.

   \section document-rendering Rendering

   To render pages of a document, you have different Document functions to set
   various options.

   \subsection document-rendering-backend Backends

   %Poppler offers a different backends for rendering the pages. Currently
   there are two backends (see #RenderBackend), but only the Splash engine works
   well and has been tested.

   The available rendering backends can be discovered via availableRenderBackends().
   The current rendering backend can be changed using setRenderBackend().
   Please note that setting a backend not listed in the available ones
   will always result in null QImage's.

   \section document-cms Color management support

   %Poppler, if compiled with this support, provides functions to handle color
   profiles.

   To know whether the %Poppler version you are using has support for color
   management, you can query Poppler::isCmsAvailable(). In case it is not
   avilable, all the color management-related functions will either do nothing
   or return null.
