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.

384a5e05dc change parameters of vips_gaussblur() 
sorry :-(

The old param (passing sigma*2 as an int) were just too confusing
coming from other packages. This new behaviour matches ImageMagick, and
almost everyone else in the world.

A new optional param lets you set the minimum amplitude as well.

    required parameters:
       width      - Image width in pixels, gint

620bff2d78 allow symbolic names for flags 
you can now use numbers or names for GFlags values, eg.:

$ vips copy 50020484-00001.png x.png[filter=avg]
$ vips copy 50020484-00001.png x.png[filter=64]

was numbers only before

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()
```
