Subject: Remove collection-less constructor overloads from most loaders
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=ae45c0397e2cb8f0a01f2f31d01c95ff3870271e

Remove collection-less constructor overloads from most loaders

These classes are extremely likely to require references to other
objects, and requiring a collection makes the code more straightforward.
