[Pixman] Strange looking text in 'dither_factor_bayer_8'

[John Emmas]

MSVC is complaining about a new function called 'dither_factor_bayer_8' 
(in pixman/pixman-bits-image.c).  The relevant code looks like this:-

     m = ((y & 0b001) << 5) | ((x & 0b001) << 4) |
     ((y & 0b010) << 2) | ((x & 0b010) << 1) |
     ((y & 0b100) >> 1) | ((x & 0b100) >> 2);

It's complaining about the symbols like '0b001' and '0b100' etc. Are 
these intended to be hex numbers?  In other words, should the code have 
looked like this?

     m = ((y & 0xb001) << 5) | ((x & 0xb001) << 4) |
     ((y & 0xb010) << 2) | ((x & 0xb010) << 1) |
     ((y & 0xb100) >> 1) | ((x & 0xb100) >> 2);

Or are they maybe some other numerical format? Thanks,

John
