CentimetersToPixels not working for marginLeft and marginTop positioning

[basjan]

My daytime job took so much time last two weeks, that I was not able to contribute. However, it has become quieter and I resynced my development tree.
All of a sudden some test code did not work any longer. For positioning an image and two textboxes, I used the following style:

$textbox = $section->addTextBox($style = array(
    'width' => \PhpOffice\PhpWord\Shared\Drawing::centimetersToPixels(4.5),
    'height' => \PhpOffice\PhpWord\Shared\Drawing::centimetersToPixels(17.3),
    'positioning' => 'absolute',
    'posHorizontalRel' => 'page',
    'posVerticalRel' => 'page',
    'marginLeft' => \PhpOffice\PhpWord\Shared\Drawing::centimetersToPixels(15.3),
    'marginTop' => \PhpOffice\PhpWord\Shared\Drawing::centimetersToPixels(9.9),
    'stroke' => 0,
    'innerMargin' => 0,
    'borderSize' => 1,
    'borderColor' => '',
    'wrappingStyle' => \PhpOffice\PhpWord\Style\Image::WRAPPING_STYLE_SQUARE
));

Using this code, no longer positions the image or textbox correctly. The position was simply marginLeft=0 and marginTop=0. When I change the relevant part into:

    'marginLeft' => 578, 
    'marginTop' => 374,   

The image and textbox are correctly positioned. Note, that 'width' and 'height' do not need to be changed.
I cannot find why this behaviour is all of a sudden present. It might be a result of static vs dynamic functions, but my knowledge in this respect is very limited.

I guess I created the bug when implying more strict value checking for styles. marginLeft and marginTop only accepted integer value. I changed the code so that both props can accept float value. These are the changes that I made to fix the bug: d9a2c4c

Bugfix pushed. Please retest. Thanks.
