When rendering text into a bitmap, I find that text looks very bad when rendered on top of an area with non-opaque alpha. The problem is progressively worse as the underlying pixels become more transparent. If I had to guess I'd say that when underlying pixels are transparent, the text renderer draws any anti-aliased 'gray' pixels as solid black.

Here are some screenshots:

Here is the code used to render the text:

```
g.SmoothingMode = SmoothingMode.HighQuality;
g.DrawString("Press the spacebar", Font, Brushes.Black, textLeft, textTop);

```
