Feature request: packing/unpacking varyings

[rraallvv]

It could be added an option to pack/unpack varyings to be able to surpass the 8 varyings limitation in some devices. For instance four floats into one vec4, two vec2 into one vec4, and so on.

You can completely avoid using anything smaller than vec4 in your shaders by using something like:

uniform vec4 u_params;
#define u_time u_params.x
#define u_foo  u_params.yz
#define u_bar  u_params.w

@bkaradzic Thanks, that would do the trick... I think I'm going to close this request.
