1619c8b1a1 fix memleak in magick6load 
IM ExceptionInfo were not being freed correctly. This patch
adds a small wrapper function and uses it to allocate and free all IM
exception objects.

Tested with im 6.9 and gm 1.3.

d35343f817 stop making tiff pyr if axis drops to 1 
TIFF pyramids of images with a very extreme aspect raio could see layer
width or height drop to 0 before the image fitted in a single tile. This
change stops pyramid creation when width or height drop to 1.

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.

d1dd41a21f strict round down on jpeg shrink 
libjpeg rounds up on shrink-on-load. In some cases this can leave a dark
line along the right and bottom edge, since it only contains (for

This change adds a crop after jpeg load so that only complete pixels are
output.
