1. Leaf blocks on fast rendering not showing correct textures 2. the mipmaping for spruce leaves and the dark oak leaves is bugged leaving a white sheen on them even when they are just 10 blocks away.

Put the summary of the bug you're having here

What I expected to happen was...:
leaves to be rendered correctly.
*What actually happened was...:
leaves on fast are all incorrect and dark oak and spruce leaves have issues with mipmapping.

Steps to Reproduce:
1. easy to see bugs with a texturepack. here's the one I am using is The CSB pack.
3. ...look at leaves.
4.... turn rendering on fancy
5...look at spruce and dark oak leaves while moving towards/ away form them. (is fixed by turning mipmapping off. )

(textures work perfectly in 1.7.10 and I've noticed in the recent versions that the opaque_leaf blocks are missing from the default texture files.)

please fix mojang and keep up the excellent work!
