-  * ''int npo2(int x)'' -- returns the lowest power of 2 greater or equal to X.+  * ''int npo2(int x)'' -- returns the next lowest power of 2 greater or equal to X.
   * ''int bitlog2(int x)'' -- returns the index of the highest used bit, aka integer binary logarithm. Useful to convert flags like ''1<<8 = 256'' back into ''8''.   * ''int bitlog2(int x)'' -- returns the index of the highest used bit, aka integer binary logarithm.
