Detailed Description

Macro access to pixels in 32-bit arrays.

1, 2, 4, 8, 16 and 32 bit data access within an array of 32-bit words

This is used primarily to access 1, 2, 4, 8, 16 and 32 bit pixels
in a line of image data, represented as an array of 32-bit words.

   pdata:  pointer to first 32-bit word in the array
   n:      index of the pixel in the array

Function calls for these accessors are defined in arrayaccess.c.

However, for efficiency we use the inline macros for all accesses.
Even though the 2 and 4 bit set* accessors are more complicated,
they are about 10% faster than the function calls.

The 32 bit access is just a cast and ptr arithmetic.  We include
it so that the input ptr can be void*.

At the end of this file is code for invoking the function calls
instead of inlining.

The macro SET_DATA_BIT_VAL(pdata, n, val) is a bit slower than
    if (val == 0)
        CLEAR_DATA_BIT(pdata, n);
    else
        SET_DATA_BIT(pdata, n);
