pub fn read_fill(reader: &mut Reader<'_>) -> Result<Option<Fill>, Error>Expand description
Parses a single bare EG_FillProperties choice (<a:noFill/>, <a:solidFill>, <a:gradFill>,
<a:pattFill>, or <a:blipFill>) from a reader positioned wherever the caller expects to find
it, skipping over any other, unrelated children along the way — unlike read_shape_properties
(which parses a whole <*:spPr>’s worth of xfrm/geometry/fill/line), this is for a host
embedding a bare fill choice on its own, outside any <*:spPr> wrapper (e.g.
powerpoint-ooxml’s own <p:bgPr> slide background, point 4). Returns None if no recognized
fill child is found before the first End/Eof at this nesting level.
