+ OpenGL ES 3.0 introduces new state on texture objects allowing a four-channel swizzle + operation to be specified against the texture. The swizzle is applied to every texture + lookup performed within any shader referencing that texture. +
++ On some WebGL implementations, texture swizzles can not be implemented in a performant + manner, meaning that applications relying on this functionality will run significantly more + slowly on those implementations. For this reason, texture swizzles are not supported in + WebGL 2.0. +
