Allan Sandfeld Jensen 4f88475a96 Allow QImage with more than 2GByte of image data 
Changes internal data-size and pointer calculations
to qssize_t.

Adds new sizeInBytes() accessor to read byte size, and
marks the old one deprecated.

README 

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.
