Subject: [PATCH] "Non well formed numeric value" error occurs in PHP 7

The $size variable in the SetFontSize function is supposed to be a float type, but a string can be passed in like "14px" causing an error in PHP 7.  Re-casting the variable is a simple solution to fix the variable type if it was incorrectly passed in.
