63a06e5f81 faster and more accurate sRGB <-> XYZ 
just use one table, since all colour channels are the same now
have more points in the float -> int direction, fewer in int -> float
faster out of range detection

fad78f8555 rework gthread usage 
glib-2.32 deprecated g_mutex_new() ... use a compat function to hide
this change

also remove the --without-threads configure flag, gthread is now
compulsory, so there was no longer any point

56f5955a24 vipsCC required the wrong version of vips 
vipsCC.pc.in was asking for vips-7.30.pc, but of course we now call it
vips.pc

4e0a433c24 openslide2vips uses multiple parallel osr reads 
open a separate openside_t for every read thread to try to get some
parallelism in decode

works, but no faster overall, since we don't ensure that each osr tile
is only fetched once --- threads need to synchronise and not overlap

we need:

- some way to get tile geometry from osr

- a threaded tilecache aligned to the osr tile boundaries

the tilecache needs to have locks and semaphores on every tile,
something like:

class tilecache:
  def generate(region):
    # lock all tiles we need, make a list of the ones that need
    # calculating
    work = []
    for tile in region:
      tile.lock()
      if tile.nodata():
        work.append(tile)
	tile.set(:in-progress)

    # calculate all empty tiles we need
    for tile in work:
      tile.calculate()
      tile.set(:data)

    # some tiles may be being made by another thread,
    # wait for them to be done
    for tile in region:
      if tile.in-progress:
        tile.wait()

    # should all have data now, paste to output and unlock
    for tile in region:
      tile.paste(output)
      tile.unlock()

    return output
