This is to make the initial window be rescaled in case the image
dimension is too large to fit the display.

24686538be PutLE{16,24}: quiet implicit conversion warnings
no change in object code

from clang-7 -fsanitize=implicit-integer-truncation
implicit conversion from type 'int' of value 39736 (32-bit, signed) to type 'uint8_t' (aka 'unsigned char') changed the value to 56 (8-bit, unsigned)

153bb3a0ef fix some clang-7 warnings:
"implicit conversion from type 'uint32_t' (aka 'unsigned int') of value xxxxx (32-bit, unsigned) to type 'uint8_t' (aka 'unsigned char') changed the value to xx (8-bit, unsigned)"

and same with signed -> unsigned conversion with truncation.

ab2dc8939f Rescaler: fix rounding error
We saturate the result to [0..255]
It's the easiest and safest, given the wide variety of scaling
range we cover: we're not using floats, so precision is always
an issue at one end or the other of the scaling spectrum.

we also use:
  round(a - floor(b))
instead of:
  floor(a - round(b))
to handle difficult cases (ratio ~= .99, e.g.)

MIPS code is still disabled (and wrong)
