Avoid backing store color space conversions.
We want the Qt backing store to be in the device color
space by default. This will avoid colour space conversions
when blitting it to screen, at the cost of a potential
loss in color accuracy.
As it turns out, CGColorSpaceCreateDeviceRGB no longer
crates a device color space but rather a generic color
space. (Since 10.4). Create the color space with a system
profile instead.
Accurate color representation needs to be supported
at some point, but this fast path should be the
default.
