GL_PIXEL_UNPACK_BUFFER bindBuffer type

[afxgroup]

I'm trying to compile Godot3 with gl4es and in bindBuffer function i get the following warning:

LIBGL: Warning, unhandled Buffer type GL_PIXEL_UNPACK_BUFFER in bindBuffer

Is this type of buffer hard to implement? Do you plan to add it?

It's tricky to implement, but I guess there can be software (i.e. slow-ish) workaround. It's part of GL 3.x need, so it's planned, but not sure when as I have very little time for gl4es.
