Guess what _doesn't_ have the same layout as a bitmap? A `til::color`. Noticed in 1.19.

if you're going to shuffle the bits around manually, why change it to COLORREF at all? Just use til::color::r, til::color::g, etc.

Sorry for the testing-fuckup. I concur with Dustin.
Additionally, the beg pointer is already a uint8_t* so we can just:
*beg++ = color.r;
*beg++ = color.g;
*beg++ = color.b;
*beg++ = color.a;(Or the other way around?)
Edit: But the DWORD code has the benefit that it can use std::fill_n so that's probably better.

We are still converting it to a COLORREF just to convert it back in the call to drawPip. Is that intentional?
