/*
  Function: gdImageCreateFromWBMP

<gdImageCreateFromWBMP> is called to load images from WBMP format
    files. Invoke <gdImageCreateFromWBMP> with an already opened
    pointer to a file containing the desired
    image. <gdImageCreateFromWBMP> returns a gdImagePtr to the new
    image, or NULL if unable to load the image (most often because the
    file is corrupt or does not contain a WBMP
    image). <gdImageCreateFromWBMP> does not close the file. You can
    inspect the sx and sy members of the image to determine its
    size. The image must eventually be destroyed using
    <gdImageDestroy>.

Variants:

<gdImageCreateFromWBMPPtr> creates an image from WBMP data (i.e. the
    contents of a WBMP file) already in memory.

<gdImageCreateFromWBMPCtx> reads in an image using the functions in
    a <gdIOCtx> struct.

Parameters:

infile - The input FILE pointer

Returns:

A pointer to the new image or NULL if an error occurred.

Example:

> gdImagePtr im;
    > FILE *in;
    > in = fopen("mywbmp.wbmp", "rb");
    > im = gdImageCreateFromWBMP(in);
    > fclose(in);
    > // ... Use the image ...
    > gdImageDestroy(im);

	im = gdImageCreateFromWBMPCtx(in);
	in->gd_free(in);
	return im;
}

/*
  Function: gdImageCreateFromWBMPPtr

Parameters:

size - size of WBMP data in bytes.
    data - WBMP data (i.e. contents of a WBMP file).
