 ## Known issues
 - If you run kernel.bin from shell, it will clear the memory map so when you load anything it will override the kernel code
 - fillCircle() in graphics.h is broken. No idea why, so no filled circles for you (i commented out the boundaryFill call in the function)
+- convertColor() doesn't work right, because i should be using floating point, but -mgeneral-regs-only doesn't let me :(
