Marc Mutz 8ab4d2028f Composition example: use std::unique_ptr instead of QScopedPointer
The use of a unique_ptr member requires that the destructor be
out-of-line, since the payload is only forward-declared in the header
file. This is good hygiene, so do it for CompositionWidget, too.

Add 'explicit' and missing = nullptr to both constructors as a
drive-by.

Qt's painting system is able to render vector graphics, images, and outline
font-based text with sub-pixel accuracy accuracy using anti-aliasing to
improve rendering quality.

These examples show the most common techniques that are used when painting
with Qt, from basic concepts such as drawing simple primitives to the use of
transformations.


Documentation for these examples can be found via the Examples
link in the main Qt documentation.
