Type-safe enum class bitmasks.
Based on work by Andre Haupt from his blog at
http://blog.bitwigglers.org/using-enum-classes-as-type-safe-bitmasks/
To enable enum classes to be used as bitmasks, use the ENABLE_BITMASK_OPERATORS
macro:
  enum class MyBitmask {
     None = 0b0000,
     One = 0b0001,
     Two = 0b0010,

Libpng warning: iCCP: known incorrect sRGB profile.

Some .png images used in pygame may get the warning read as "libpng warning: iCCP: known incorrect sRGB profile". To solve this I have searched and found the solution by using ImageMagick. After installing, single file can be fixed by calling convert <in_img> -strip <out_img>, but to make it fixes every wanted images in path we'll need to modify just a little bit.

Create .bat file contains the following code and place this .bat in the folder that want to be fixed and run to finish it out.

@echo off
ping -n 2 127.0.0.1 > nul

echo this batch will convert ".png" using -strip option from ImageMagick.
