sokol: shader v compiler error about v HOT 3 OPEN

If you change one of the names there, you have to also change the corresponding name in simple_shader.glsl:
in vec4 aposition;

yeah, its a pretty simple fix, and didn't take long to notice. but the compiler said I should report it as a bug. granted this isn't pure v code. I just thought I should report it.

from v.

Yes. Thank you for reporting it.

We should think of a way to handle those better (since V can know about the shader variables from its v shader tool, it should be able to offer more useful errors for that specific situation).
