Build fails with no method found error

Trying to build on ARM linux with rustc 1.7 nightly:

I'd asked you about gles on linux a while ago (can't remember the issue) but now that I've tried to build zoc for OpenGL, it's obvious another Makefile target is going to be needed.

[ozkriff]

Hmm, it compiles on travis (rustc 1.7.0-nightly (d0bac3f14 2016-01-18)):

https://travis-ci.org/ozkriff/zoc/jobs/101669943

[MagaTailor]

I managed to compile zoc using stable 1.5 after hackishly fixing glutin due to this ARM issue.

However under 1.7 that wouldn't work so easily due to wayland not compiling so it had to be updated to 0.5.8 first and then cargo update'd. That must have broken some dependencies.

I've already got used to doing this and so I completely forgot to mention the fact. Sorry for that.

[MagaTailor]

I suggest updating the README with info about OpenGL version requirements. For example, I tried to run the binary on ARM Linux @ 16bpp:

GL_VERSION: 2.1 Mesa 10.1.3
GLSL_VERSION: 1.20
GL_VENDOR: Mesa Project
GL_RENDERER: Software Rasterizer
thread '<main>' panicked at '0:1(1): error: syntax error, unexpected $undefined
', src/zgl/src/shader.rs:168

Normally, if the default OpenGL 3.3 is required it aborts immediately so maybe it's something else? (colour depth?)

EDIT
Never mind, I already confirmed it compiles.
