If the target is to make a user-friendly Windows API monitor, there are tons of ready-to-use tools lying around:
	Huorong Sword: https://www.huorong.cn/
	API Monitor: https://www.rohitab.com/apimonitor
	Process Monitor from Sysinternals: https://docs.microsoft.com/en-us/sysinternals/downloads/procmon
So my version of PEDoll will NOT focus on pretty-printing Windows APIs, but on better interoperability with internal procedures

----------

registers to preserve:
	x86
		pushfd/popfd
		(pushad/popad) eax, ecx, edx, ebx, esp, ebp, esi, edi
	x64
		pushfq/popfq
		rax, rcx, rdx, rbx, rbp, rsp, rdi, rsi, r8, r9
	(?) FP registers
		st0 ~ st7 (should be empty according to calling convention)
		xmm0, xmm1, xmm2, xmm3

calling conventions:
	x86
		cdecl/stdcall (stack)
		fastcall (ecx, edx, stack)
	x64
		msvc (rcx, rdx, r8, r9, stack)
		gcc (rdi, rsi, rdx, rcx, r8, r9, stack)

*IMPORTANT*: Mark color outputs as a enhancement idea, but not a necessary one

`dump` formats:

"Commands.Dump.Header" => "Dump #{0} from hook \"{1}\" ({2} bytes), under format \"{3}\":\n\n"

hex(default)
Similar to (but not the same as) `hexdump -Cv`, 4 part separated with double spaces:
 Offset /\        8 bytes        /\        8 bytes        /\  ASCII or '.'

Color: unconverted '.'s are dark gray, bytes are white, others are default color

raw
Console: like ASCII column in "hex", unconverted '.'s are dark gray, others are white
File: untouched

ansi, unicode, utf8
Try Encoding.(Default|Unicode|Utf8).GetString() and give out error if exception thrown
NOTE: Some of the encodings supports replacing unknown characters into '?'s or similar things

x86, x64
