/* Create a bitmap context. The context draws into a bitmap which is
* `width' pixels wide and `height' pixels high. The number of components
* for each pixel is specified by `colorspace', which also may specify a
* destination color profile. The number of bits for each component of a
* pixel is specified by `bitsPerComponent', which must be 1, 2, 4, or 8.
* Each row of the bitmap consists of `bytesPerRow' bytes, which must be at
* least `(width * bitsPerComponent * number of components + 7)/8' bytes.
* `data' points a block of memory at least `bytesPerRow * height' bytes.
* `alphaInfo' specifies whether the bitmap should contain an alpha
* channel, and how it's to be generated. */
