Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

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.
