db4fe60405 fix mapim offsets
pixels were not being offset by the stencil origin, so interpolators
like bicubic could fail

ac4897abee Fix up vips_text()
Fixes two issues:

1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.

2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.

d06c2fee22 use exif_tag_get_name_in_ifd() everywhere
exif tag names change with the ids they appear in, so you must always
use exif_tag_get_name_in_ifd(), not exif_tag_get_name()

ca6410e1a6 make members and getters "const" in cpp api
eg. VImage::width() is now

	int VImage::width() const;

ie. it does not alter the image objects. In factr we can mark almost all
members const.

d251b37d92 add vips_argument_get_id()
We had a global we incremented to allocate property ids, but of course that
won't work with DLLs. Instead, add vips_argument_get_id() and call that to
allocate new prop ids.

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.

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.
