glyph-vector-2 svg example, bitmap inverted and also scaling wrong.

[HinTak]

I have rewritten the vector outline sample ( output at
#55 (comment) ) and is on to the composite bitmap +output sample in vector-2, and found it to be wrong in a few ways:

• the bitmap in the background is inverted. It is actually a g, but I thought it was a stylized 'a',, when I first looked at it!

• the scaling between the outline and the bitmap is meaningless - the outline is scaled to the width of "any-filled pixels", which means it is a lot wider and taller than the actual outline used for calculating the bitmap (half-pixels means it is a light-shade, etc), by up to almost two squares in both directions. In the above, the bitmap is 17x 25, and the outline is scaled to 17x25 - but it can be seen quite clearly from the figure above, that the bitmap is really calculated from an outline which was only just over 15 pixels wide in this scale.

This is how it should look (from the still-in-dev rewrite - not doing svg yet)

Screenshot from ftgrid (one of the the freetype demo programs) - This is the authoritative answer as how freetype does it.

It seems the alignment in mine is still a bit off.

edit correct version - note bottom of g. Was scaling by integer from top instead of floating point.
