2fee131b9e mandelbrot: use period detection depening on left pixel and not the 
previous calculated pixel, this is more accurate due to the last
calculated often being farther away.

96949dafcc Replace all strcasecmp/strncasecmp usages. 
All current usages of it are incompatible with localization.
For example strcasecmp("i", "I") != 0 is possible, but would
break many of the places where it is used.
Instead use our own implementations that always treat the data
as ASCII.
