Fix VersionNumber: Non digits cut off pattern was '\D.*' and cut off digits in case leading non digits appear.

'\D.*' matches a leading non-digit and then any character.

First the string is tokenized by delim:
  "OpenGL ES GLSL ES 1.0.16" -> "OpenGL ES GLSL ES 1", "0", "16"

Enhance pattern as follows and access collected group if matching:
        // group1: \D* == leading non digits, optional
        // group2: \d* == digits
        // group3: .*  == any pending chars, optional
        final java.util.regex.Pattern nonDigitsCutOff = java.util.regex.Pattern.compile("(\\D*)(\\d*)(.*)");

Reorganized storage from atomic values to int[3] array, allowing simple pattern matching loop.

Added unit test.
