I edited my previous comment while the previous comment was being typed. However, for the curious, the setting in question is under keyboard properties in windows.

comment Fastest way to factor powers of two?
On modern cpus, there is a primitive instruction for doing this. Without that, there is still a faster way -- by adopting the De Bruijn method of finding integer log_2 -- than the solution listed in the Integer class.

comment Looking for an efficient integer square root algorithm for ARM Thumb2
Yep, this is probably the fastest you can do on a CPU with division but without a FPU or extended bit manipulation instructions. It is worth noting that the 64 bit version of the algorithm may get better precision for large numbers than an IEEE 754 double on some computers.

comment Is it possible to detect window occlusion
If I understand you correctly, I already knew that Relying on builtin Java2D behaviour would not be enough. To save on resources when window is hidden.
