PNGDataSource is commented

[am2222]

Hello,
I have two questions, first is there any reasons that PNGDataSource is commented in the example?
Also is there any chance that this package gets updated? I see some conflicts with the latest version of three.js and also some glitches when we use satellite tile material on the generated surface

hi @am2222 , thanks for the issue.

I'll ask internally if this is still to be maintained or whether this project should be archived.

@NicolasNeubauer, can you comment? I see you made the initial commit.

@nzjony Thanks. It managed to compile it with the latest version of the packages but seems it has room for improvement.

@NicolasNeubauer It seems that function was commented from the beginning
