Summary0006099: Ugly seams on the $reflection cubemap
Description$reflection cubemap looks incorrect.

See secreenshot:
1) Top face is visibly brighter than adjacent faces
2) There are visible discontinues between right-bottom and left-top faces
3) Seams between all faces [I checked earlier glEnable(GL_TEXTURE_CUBE_MAP_SEAMLESS) doesn't remove them]

P.S. This map has no skybox texture, so it's not related to wrong map supplier skybox cubemap.
Steps To Reproduce1) Establish sphere reflective surface
2) Make it reflect the environment.
3) See the subject
TagsNo tags attached.
Checked infolog.txt for Errors

GL_TEXTURE_CUBE_MAP_SEAMLESS only works with unclamped texcoors and would not fundamentally solve face discontinuities (which were caused by rendering with a wrong AR), I'll add an option for it.

the extra brightness might be a bug with z=y cameras but I did not track it down.

I'm pleased to report that seams and other artifacts are gone in 104.0.1-941-gfcc4751.

P.S. Can you give some guidance on: https://springrts.com/mantis/view.php?id=6084
(I'll try to implement it myself upon your advice)
