This makes the code a little clearer. In most cases, it’s not a functional change. In a few cases, the values are different. I believe the original values were incorrect (accidentally transposed, perhaps). This never caused an issue because they were all immediately overwritten during construction of a `GParamSpec`: these values were defaults in the `instance_init` vfunc of the `GTypeInstance` for a `GParamSpec`, but the actual min/max for the `GParamSpec` instance were immediately written over them in the constructor (such as `g_param_spec_int()`). Spotted in !4593. Signed-off-by: Philip Withnall <pwithnall@gnome.org>
