This depends on what you exactly mean with `loading' and
`rendering'...
IMHO, your assumption is not correct: Assuming that the default
rendering mode of FreeType is always grayscale rendering
(FT_RENDER_MODE_NORMAL), this principle was already violated with the
introduction of FT_LOAD_COLOR for color bitmaps since you actually get
color bitmaps! Theoretically, grayscale bitmaps should have been
returned by default. For Joe User it is thus obvious that
FT_LOAD_COLOR automatically gives coloured outline glyphs even for
FT_RENDER_MODE_NORMAL.

We need both, as I've tried to implement in `master': FT_LOAD_COLOR
should trigger a standard case with some default blending; for finer
color and blending control separate functions should be provided to
allow direct layer access.
