David Turner e13391333f Make macros for header file names optional. 
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style. 
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from

Bug introduced after release 2.8.

* src/base/ftbitmap.c (ft_bitmap_assure_buffer): We use
`FT_QALLOC_MULT', which doesn't zero out the buffer.  Adjust the
bitmap copying code to take care of this fact.

Also reported as

  https://bugs.chromium.org/p/chromium/issues/detail?id=791317

* src/base/ftbitmap.c (ft_bitmap_assure_buffer): If increasing the
bitmap size needs a larger bitmap buffer, assure that the new memory
areas are initialized also.

Werner Lemberg a3dd6d99a4 Fix multiple calls of `FT_Bitmap_Convert'. 
The documentation of `FT_Bitmap_Convert' says that multiple calls do
proper reallocation of the target FT_Bitmap object.  However, this
failed for the sequence

  non-empty bitmap
  empty bitmap
  non-empty bitmap

Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
buffer if it became too small; it didn't make the buffer smaller.
For an empty bitmap following a non-empty one, only the buffer
dimension got set to zero, without deallocation.  If the next call
was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
triggered.

* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
buffer to the correct size.

* docs/CHANGES: Document it.
