6368ab0649 add switches to disable rad, analyze and ppm 
vips has built-in support for rad, analyze and ppm ... add configure
switches to disable these readers

useful to reduce the attack surface in some applications

c1f1a7c1b3 improve sharpen for screen work 
it was a bit granular (since it was designed for offset work), make sharpen
easier to adjust for smaller effects

- new 'sigma' parameter
- greater parameter range
- more self-tests

8e667fbb3e still not quite there 
works, but is no faster, how odd

john@kiwi:~/pics$ time vips magickload nipguide.pdf[40] x.tif
real	0m0.244s
user	0m0.212s
sys	0m0.040s

$ time vips magickload nipguide.pdf x.tif --page 40
real	0m7.035s
user	0m6.900s
sys	0m0.152s

both give same result

de65da85b9 smarter conversion of float masks to int 
we were just rint()ing masks going from float -> int, but this could
give bad results in some cases, with output images becoming darker
or lighter, as individual elemets moved up or down

now we adjust the output scale to try to keep the overall brightness
the same, if we can

6e2135d8b5 mask builders take prec, not integer 
vips_gaussmat() and vips_logmat() used to default to float, but
vips_conv() defaulted to int ... so this failed:

	vips gaussmat m.v 2 0.1 --separable
	vips convsep k2.jpg x.jpg m.v

since we were using a small float mask with an integer convolution

This change makes everything int by default, with gaussmat having a new
param called --precision whose arg can be int or float.

The old @integer param is deprecated.

154796a8dc rename VIPS_ANGLE_0 as VIPS_ANGLE_D0 
and other similar cases

VIPS_ANGLE_0 becomes Vips.Angle.0 in Python, which is very inconvenient, so we
rename ... the D stands for degrees, I think

a370e5003e vips array types are more binding-friendly 
this all works now:

```python
from gi.repository import Vips

a = Vips.ArrayDouble.new([1,2,3])
a.get()

a = Vips.ArrayInt.new([1,2,3])
a.get()

a = Vips.ArrayImage.new([c, d, e])
a.get()
```
