Fixes several files incorrectly stated a different license from the actual project, as well as the copyright headers included in all files. This change has no effect on the licensing terms, it should clear up a bit of confusion by contributors. Plus the files get a bit smaller, and we have less duplicated information across the entire project. Overall the project is GPLv2 if not built with Qt, and GPLv3 if it is built with Qt. There are no parts licensed under a different license, all have been adapted from other compatible licenses into GPLv2 or GPLv3.

/* gs::mipmapper is an attempt at adding dynamic mip-map generation to a software
|
|
* which only supports static mip-maps. It is effectively an incredibly bad hack
|
|
* instead of a proper solution - can break any time and likely already has.
|
|
*
|
|
* Needless to say, dynamic mip-map generation costs a lot of GPU time, especially
|
|
* when things need to be synchronized. In the ideal case we would just render
|
|
* straight to the mip level, but this is not possible in DirectX 11 and OpenGL.
|
|
*
|
|
* So instead we render to a render target and copy from there to the actual
|
|
* resource. Super wasteful, but what else can we actually do?
