[Devel] truetype loader crashes in current CVS version

[Sven Neumann]

Hi,

I'm experiencing crashes with the current CVS version whenever I try
to load a truetype font. If FT_CONFIG_OPTION_INCREMENTAL is undefined
(this is the default), the TrueType loader crashes in line 852 of
src/truetype/ttgload.c when it tries to access face->glyph_locations.
This pointer is always NULL since the array is allocated in
TT_Load_Locations() which is only called if FT_CONFIG_OPTION_INCREMENTAL
is defined (see ttobjs.c line 203).

Another unrelated note: I think that FT_Error should be initialized to
0 in FT_Glyph_To_Bitmap() since it will otherwise be used uninitialized
when this function is called with a bitmap glyph. Here's a simple patch
that fixes this problem:
