/*
  Function: gdImageCreateFromXpm

<gdImageCreateFromXbm> is called to load images from XPM X Window
    System color bitmap format files. This function is available only
    if HAVE_XPM is selected in the Makefile and the Xpm library is
    linked with the application. Unlike most gd file functions, the
    Xpm functions *require filenames*, not file
    pointers. <gdImageCreateFromXpm> 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 an XPM bitmap format
    image). You can inspect the sx and sy members of the image to
    determine its size. The image must eventually be destroyed using
    <gdImageDestroy>.

Parameters:

filename - The input filename (*not* FILE pointer)

Returns:

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

Example:

> gdImagePtr im;
    > FILE *in;
    > in = fopen("myxpm.xpm", "rb");
    > im = gdImageCreateFromXpm(in);
    > fclose(in);
    > // ... Use the image ...
    > gdImageDestroy(im);
