Fix reading of signed integers from files on 64bit platforms.
...
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension. For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.
We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.
* include/freetype/internal/ftstream.h, src/base/ftstream.c
(FT_Stream_Get*): Replace with...
(FT_Stream_GetU*): Functions which read unsigned integers.
Update all macros accordingly.

* src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
error codes only if pedantic hinting is active. At the same time,
try to provide sane values which hopefully allow useful
continuation. Exception to this is CALL and LOOPCALL – due to
possible stack corruption it is necessary to bail out.

[truetype] Fix handling of MIRP instruction.
...
Thanks to Greg Hitchcock who explained the issue.
* src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
`>' since the description in the specification is incorrect.
This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
65 medium' at 15ppem.

[raster] Make bbox handling the same as with Microsoft's rasterizer.

Right before B/W rasterizing, the bbox gets simply rounded to
integers. This fixes, for example, glyph `three' in font `Helvetica
Neue LT Com 65 Medium' at 11ppem.
Thanks to Greg Hitchcock who explained this behaviour.

[raster] Reduce jitter value.
...
This catches a rendering problem with glyph `x' from Tahoma at
10ppem. It seems that the increase of the precision in the change
from 2009-06-11 makes a larger jitter value unnecessary.
* src/raster/ftraster.c (Set_High_Precision): Implement it.

[raster] Handle drop-outs at glyph borders according to Microsoft.
...
If a drop-out rule would switch on a pixel outside of the glyph's
bounding box, use the right (or top) pixel instead. This is an
undocumented feature, but some fonts like `Helvetica Neue LT Com 65
Medium' heavily rely on it.
Thanks to Greg Hitchcock who explained this behaviour.
* src/raster/ftraster.c (Vertical_Sweep_Drop,
Horizontal_Sweep_Drop): Implement it.
