When using OpenGL ES 3.1, we either need to emit a precision qualifier,
or set a default precision.
Since it's not unthinkable that we'd want to forward lowp/mediump
in the future, let's use the precision qualifier so it's easier
to get this right later on.
This gets rid of a shader compile error.

The TGSI FBFETCH instruction is used for implementing framebuffer-reads
when doing for instance advanced blends. It's used by both

Sadly, libepoxy doesn't yet support the glFramebufferFetchBarrierEXT
function needed to implement this on top of
EXT_shader_framebuffer_fetch_non_coherent itself, so let's just implement
it on top of EXT_shader_framebuffer_fetch instead for now.

If a shader uses TGSI_INTERPOLATE_LOC_SAMPLE, we need to emit
the "sample"-keyword for the input-variable in the fragment
shader.
Since the "sampler"-keyword is a GLSL 4.00 feature, this
requires us to enable GL_ARB_gpu_shader5. Unfortunately, opting
in carefully on this is a bit trickier than for most other
extensions, because we patch up vertex, geometry or tesselation
evaluation shader outputs to match the fragment shader inputs.
Since the previous patch adds padding for the require-statement
directly after the #version string, we can just overwrite that
padding with the require statement.
