1a95b2df89 fix tga header read 
When you ping() an image with imagemagick to get the header, some format
loaders (eg. TGA) don't set all the fields. In this case,
image->colormap was not set and that made GetImageChannelDepth() crash.

Work around this, at least in this case, by allocating a colourmap
ourselves if none is set.

b085908558 remove vips7 stuff from API 
You must now include vips7 support explicitly with

	#include <vips/vips7compat.h>

in your code just after including `vips.h`.

The old vips7 names, such as `Rect`, were starting to cause problems
with other packages like opencv.

265fb2a825 improve colourspace guessing in icc 
icc_transform does a better job of guessing the colourspace of an image -- if
the colourspace has not been set (generic multiband), it'll look at the
image bands instead and guess from that

80a0a24cfa Fixed deadlock in vips_cache_drop_all if vips__cache_dump is true 
Both vips_cache_drop_all and vips_cache_print acquire vips_cache_lock
on entry, but vips_cache_drop_all calls vips_cache_print internally if
vips__cache_dump is true, leading to a deadlock situation.
This commit solves the issue using one further level of indirection
and a new vips_cache_print_nolock function.

d3439f4d49 Fix wrong value for VIPS_FOREIGN_PNG_FILTER_ALL 
The value is derived by oring all the filter flags:

    0x08 | 0x10 | 0x20 | 0x40 | 0x80 == 0xf8

The value was also checked against PNG_ALL_FILTERS in png.h.

c410dc2db8 add format option to magickload 
Some magick coders (eg. ICO) don't sniff the filetype from the data, so
when you try to load from a string, imagemagick is unable to pick the
right decode path.

Add a @format option so callers can hint the filetype.

d1dd41a21f strict round down on jpeg shrink 
libjpeg rounds up on shrink-on-load. In some cases this can leave a dark
line along the right and bottom edge, since it only contains (for
example) 1/4 of a pixel of data.

This change adds a crop after jpeg load so that only complete pixels are
output.
