Correction for the fix for Bug 3508 - Persistent storage support breaks Linux compatibility. A 2nd `make install' will fail attempting to create symlink libnvmemmory.so already created by 1st install. Install should pre-emptively delete it.

This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
