1. ensure that all of the following works (write down generated filename in each case)
   1. test watermark image ("Field" tag with "format" parameter, that will make use of "wm" option, e.g. <inp2:u.current_Field name="PrimaryImage" format="resize:200x100;wm:img/watermark_1_small.png|-5|-5"/>)
   2. test default image ("Field" tag with "format" parameter, that will make use of "default" option, e.g. <inp2:u.current_Field name="PrimaryImage" format="resize:200x100;default:img/watermark_1_small.png"/>)
   3. test compressed js/css file ("m_Compress" tag with "files" parameter, e.g. <inp2:m_Compress files="platform/inc/script.js"/>)
2. rename folder with In-Portal (make sure you have closed PhpStorm before)
3. reload test page (make sure to update In-Portal folder name in the browser too)
4. confirm that names of all 3 generated files are still the same (without this patch names will differ)

P.S.
Use only existing watermark/default/script files in tests. Create ones if needed.
