When data defining font size the PAL layer-level font size appears to be used for initial calculation of label placement, with the data defined value (that should be overriding the layer level size) applied later when drawing the label. I have not investigated this bug much, but have seen issues with it. I intend to fix it, though I am reporting it now so it does not get overlooked or forgotten.
Example of issue: when data defined font size is 10pt and the layer-level size is 20pt, curved labels will be spaced/calculated at 20pt, but rendered at 10pt. (Useful for faking letter-spacing, but is actually a bug.)
