Update ImageWorkshopLayer.php

[mbeech]

Fixing a bug when adding a layer on top after resizing with converse proportions.

To recreate the bug:

$watermark = PHPImageWorkshop\ImageWorkshop::initFromPath('watermark.png');
$watermark->opacity(20);

$image = PHPImageWorkshop\ImageWorkshop::initFromPath('image.png');
$image->resizeInPixel(770, 770, true, 0, 0, 'MM');
$image->addLayerOnTop($watermark);

Expected result:
image.png resized to 770 x 770px with the watermark on top with opacity 20%

Actual result:
blank image resized to 770 x 770px with the watermark on top with opacity 20%

Hello @mbeech you found a beautiful bug !

But you can't apply a mergeAll, because users do not necessarily want to have merged layers (if the layer has sublayers, sublayers have to be distinct, and not all merged in one after a resize).

Anyway, thank you for reporting the bug and proposing a solution, I'm working on a fix ;)

Hi Sybio

Yes I did think that, but I tried so much that was the only thing I could get working! Let me know if you need any help with the fix.

Thanks
