+/* 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. */
