Main: fix spelling error

[chillywillysoft]

I introduced a spelling error (frustrum instead of frustum) with this commit. Hopefully fixing it isn't too breaking. I doubt many people have tested for frustums since 14 came out and updating any broken code should be trivial.

the issue forward compatibility. Some code might be written against 14.0 due to distro packaging or similar. This must continue working with any 14.x release.

Therefore, please use this pattern:

ogre/Components/RTShaderSystem/include/OgreShaderSubRenderState.h

Lines 57 to 60 in 3f0a656

	/// @deprecated use #SRS_SHADOW_MAPPING
	_OgreRTSSExport extern const String SRS_INTEGRATED_PSSM3;
	/// shadow mapping receiver with multiple lights or single PSSM light with up to 3 custom splits.
	_OgreRTSSExport extern const String SRS_SHADOW_MAPPING;

For 14.1.x this still would break backwards compatibility. I will merge this in time for 14.2. Set to draft so I dont merge it by accident.

[chillywillysoft]

Sounds good. But just so I understand/learn, how does this break backwards compatibility? The string didn't change, it still has the old constant name and now it has a new constant name.

how does this break backwards compatibility?

imagine someone writes code against 14.1.1 (with this change) and then needs to deploy it with 14.1.0

Ah, I think I see. Not to nitpick but if I understand correctly, what you call not backward compatible is what semver calls "new, backward compatible"? So waiting for the next minor makes perfect sense.
