This loop copy as many bits that it can each time, crossing<p>

   116

successively bytes<p>

   117

Bit missalignement between src and dest<p>

   118

We can now get src and align it to dest<p>

   119

Compute the nb of bit we will be able to copy<p>

   120

Create a mask that will serve in:<p>

   121

<ul>

   122

<li>Filtering src</li></ul>

   123

<p>

   124

<ul>

   125

<li>and erase bits where we write, preserve where we don't</li></ul>

   126

<p>

   127

Then write.<p>

   128

Compute next time cursors for src<p>

   129

cross boundary ?<p>

   130

First bit<p>

   131

Next byte<p>

   132

Compute next time cursors for dest<p>

   133

First bit<p>

   134

Next byte<p>

   135

And decrement counter.
