Wacky text alignment about fontdue

[mooman219]

From your image it's fairly obvious that your code is miss-interpreting the y position and/or height. This is an example of that happening (Note the similarity to your issue):

And here it is when interpreting the y/height from fontdue correctly:

Note: The y coordinate is the bottom edge of the glyph, and height expands upwards. These are the relevant docs:

pub struct GlyphPosition {
    /// Hashable key that can be used to uniquely identify a rasterized glyph.
    pub key: GlyphRasterConfig,
    /// The left side of the glyph bounding box. Dimensions are in pixels, and are alawys whole
    /// numebrs.
    pub x: f32,
    /// The bottom side of the glyph bounding box. Dimensions are in pixels and are always whole
    /// numbers.
    pub y: f32,
    /// The width of the glyph. Dimensions are in pixels.
    pub width: usize,
    /// The height of the glyph. Dimensions are in pixels.
    pub height: usize,
}
