* massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.

* include/freetype/internal/sfnt.h (SFNT_Interface): New method
`load_strike_metrics' used to load the strike's metrics.
* src/sfnt/sfdriver.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
src/sfnt/ttsbit0.c: New function `tt_face_load_strike_metrics'.
* src/pfr/pfrobjs.c (pfr_face_init): Set FT_Bitmap_Size correctly.
* src/winfonts/winfnt.c (FNT_Face_Init): Use `nominal_point_size' for
nominal size unless it is obviously incorrect.
* include/freetype/freetype.h (FT_Bitmap_Size): Update the comments on
FNT driver.
Introduce new size selection interface.
* include/freetype/internal/ftdriver.h (struct FT_Driver_ClassRec_):
Replace `set_char_sizes' and `set_pixel_sizes' by `request_size' and
`select_size'.
* include/freetype/freetype.h (FT_Select_Size, FT_Size_Request_Type,
FT_Size_Request, FT_Request_Size, FT_Select_Size), src/base/ftobjs.c
(FT_Select_Size, FT_Request_Size): API additions to export the new
size selection interface.
* src/base/ftobjs.c (FT_Set_Char_Size, FT_Set_Pixel_Sizes): Use
`FT_Request_Size'.
* include/freetype/internal/ftobjs.h (FT_Match_Size),
src/base/ftobjs.c (FT_Match_Size): New function to match a size
request against `available_sizes'. Drivers supporting bitmap strikes
can use this function to implement `request_size'.

src/type42/t42objs.c, src/type42/t42objs.h, src/winfonts/winfnt.c:
Update to new size selection interface.

src/cff/cffobjs.h, src/truetype/ttdriver.c, src/truetype/ttgload.c,
src/truetype/ttobjs.c, src/truetype/ttobjs.h: Update to new size
selection interface.
Make `strike_index' FT_ULong and always defined.
Use `load_strike_metrics' provided by SFNT interface.
