Fix buttons/texts missing when mipmap ON in Tactic Ogre

[dbz400]

Issue #2286

[solarmystic]

@raven02

Would this also fix other games with Mipmapping issues? Does it need to be tested?

[dbz400]

May be .However i don't have any other games that have mipmapping issue so far .

[solarmystic]

If this helps out, I will be able to close #2286

Also @raven02, are you sure this won't break your other game that needs Mipmapping to be ON like this one? :-

There was a reason why @hrydgard reverted the commit you're about to enable again (he commented it out with // as you can see in the code), you better test out that game first.

(I don't know what the title is, I don't recognise the Chinese/Japanese characters in your screenshot)

[hrydgard]

x || !x = true

so this will always happen, which also means that mipmapping is now always turned off. I don't think that should be necessary (Although I really don't understand what the real problem is here, it's really weird).

I think this approach would be better ?

bool noMip = (gstate.texlevel & 0xFFFFFF) == 0x000001 || (gstate.texlevel & 0xFFFFFF) == 0x100001 ;  // Fix texlevel at 0

// Mipmapping OFF 
if (!g_Config.bMipMap || noMip ) {
    magFilt &= 1;
    minFilt &= 1;
}

[hrydgard]

That seems fine if it solves it.

I see. Already tested , it is working well .

I think one of the reason @hrydgard revert that commit because it only partially working at that time . As @unknownbrackets , button did work somehow but not texts . Right now both should be rendered correctly when mipmap ON.

Regarding another game that need mipmap ON , i think it is another issues

1. It works on windows only but not on Android
2. It works ok when read FBO to memory ON which is similar issue to 3rd birthday
