[isobaric]

Run: PhpOffice\PhpPresentation\IOFactory::load("demo.pptx"); get some error message: PhpOffice\PhpPresentation\AbstractShape::setWidth(): Argument #1 ($pValue) must be of type int, float given, called in /xxx/vendor/phpoffice/phppresentation/src/PhpPresentation/Reader/PowerPoint2007.php on line 972

error file: change return type float to int can fixed it;

From 1.0.1 to 1.0.5 something broke pptx files.
