Update on this:
It's not a regression; the text was black last year because at that time, pixels that weren't rendered were left black, and today such pixels are left transparent.

The reason that nothing is shown is because AxialShadingContext is created with a wrong AffineTransform, that has giant scale values. That AffineTransform is related to the text rendering (drawString()) and is OK for that, but not for the shading. When I replace the wrong AffineTransform with a standard one for that dpi (e.g.  [4.16, 0, 0][0, 4.16, 2508] for 300dpi) I get a perfectly shaded text.

> This is also somewhat of a regression: in PDFBOX-615, the file color_gradient.pdf-1.png had the text rendered, although in black. Currently, the text is invisible.
