/**
 * Shared global constants.

 * expressions (constants), and are inlined by the Java compiler at all places which reference these constant fields.
 * Therefore, changing the value of these constant fields will have no effect on already compiled code.</p>
 * 
 * <p>In addition, it is presumed that a large portion of these constant fields (such as those prefixed with {@code
 * DEBUG_} are used as 'flags', for manually toggling code meant for use by Mojang developers in debugging. Therefore,
 * optimizing compilers (which include the Java compiler) may omit the code hidden behind disabled flags, and will
 * result in these flags having no apparent use in the code (when in reality, the optimizing compiler has removed the
 * code which uses them).</p>
