78acd9b7a0 use a better name for the dzsave temp dir 
see https://github.com/jcupitt/libvips/issues/242

dzsave with deepzoom layout and fs container writes a temp dir called
dzsave-temp-324857 or similar, and makes sure that this directory does
not exist

after write, the foo_files and foo.dzi files are picked out to the
current dir and the temp removed

346a9e70c0 remove --disable-cxx flag 
it was getting too hard to support :( automake now generates libtool
lines before configure runs, so it can't know we don't want a C++ link

   gamma in out
where:
   in           - Input image, input VipsImage
   out          - Output image, output VipsImage
optional arguments:
   exponent     - Gamma factor, input gdouble
  			default: 2.4
			min: 1e-06, max: 1000

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.
