*
* This extension allows using up to 4 different shared palettes
* with ColorTableEXT. The following constants are provided
* to use as targets for ColorTableExt:
*
* - SHARED_TEXTURE_PALETTE_0_KOS
* - SHARED_TEXTURE_PALETTE_1_KOS
* - SHARED_TEXTURE_PALETTE_2_KOS
* - SHARED_TEXTURE_PALETTE_3_KOS
*
* In this use case SHARED_TEXTURE_PALETTE_0_KOS is interchangable with SHARED_TEXTURE_PALETTE_EXT
* (both refer to the first shared palette).
*
* To select which palette a texture uses, a new pname is accepted by TexParameteri: SHARED_TEXTURE_BANK_KOS
* by default textures use shared palette 0.
