a9af691481 Fix handing of `FT_Bool'. 
Before this commit we had code like

  (FT_Bool)( globals->glyph_styles[gindex] & 0x8000)

Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like

  (unsigned char)( 0x8532 & 0x8000)

which in turn expanded to

  (unsigned char)( 0x8000)

and finally yielded 0x00 – i.e., false – not as expected.

Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.

* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.

*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.

793a9ff9f5 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Another tweak. 
This one should be clearer. When the rounded monochrome bbox collapses
we add a pixel that covers most if not all original cbox.

335528e11e Improve auto-hinter handling of bitmap fonts (#54681). 
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'.  However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path).  It appears that the
auto-hinter should not be called when the face doesn't have
outlines.  The current test for using the auto-hinter in
`FT_Load_Glyph' checks if the driver supports scalable outlines, but
not if the face supports scalable outlines.

* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.

This adds pixels in case a contour goes through the center
