Allan Sandfeld Jensen 5f59207bd3 Optimize drawing to and from generic formats
When drawing to and from the less common formats most of the cpu time
is spend in conversion. The conversion method is rather slow due to
using variable shifts and masks that the compiler does not have a chance
to optimize.

This patch changes the conversion methods to being templates fed by
constexpr methods. This allows the compiler to fully optimize the methods
yielding 2x->5x speedups.

The reliance on constexpr however means the optimized methods are only
used under C++11.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
