I was thinking about that.  Is it not the case though, that if the glyph
ends at the edge of its bounding box, then TeXmacs does not dither
outside the raster representation of the bounding box ?  That is,

  vector         raster
+--------+     +--------+ <- bounding box
|        |     |        |
|        |     |        |
+--------+     +--------+
|XBLACKXX|     |XBLACKXX|
|XBLACKXX| --> |XBLACKXX|
+--------+     +--------+
|        |     |        |
|        |     |        |
+--------+     +--------+

and not

  vector          raster
+--------+      +--------+ <- bounding box
|        |      |        |
|        |      |        |
+--------+      +--------+
|XBLACKXX|     X|XBLACKXX|X
|XBLACKXX| --> X|XBLACKXX|X
+--------+     ^+--------+
|        |     ||        |
|        |   +-+|        |
+--------+   |  +--------+
             |
             |
        antialiasing
         "spillover"

If this is the case, all will be well.
