Elias Naur 05485a79a6 app/internal/srgb: rename NewSRGBFBO to New and SRGBFBO to FBO
The srgb package was recently created to contain just the sRGB
emulation, but the names weren't shortened accordingly.

Elias Naur 94fdc26cb5 app,app/headless: expose Backends from window and headless contexts
This is a refactoring change to prepare for another gpu.Backend
implementations.

Notably, app/loop.go no longer imports gpu/gl.

Elias Naur 3b6646933d gpu: expose the rendering implementation
The rendering implementation is needed for using Gio UI with external
window libraries such as GLFW. Expose it in the new package gpu.

Elias Naur 251c075093 app/internal/gl/impl: extract platform dependent opengl bindings
We'd like to support Gio using a different renderer binding than
the builtin. A first step is to define the Functions interface
in package gl, and extract the concrete implementations to a
separate package.

Aaron Bieber fdaf891732 app: Enable building on OpenBSD
Currently the golang.org/x/sys package is missing the Pipe2 call for OpenBSD.
The call exists on OpenBSD, it just isn't exposed.

This diff was tested buy adding the Pipe2 call and setting:

   go mod edit -replace=golang.org/x/sys=/pat/to/modified/sys

Elias Naur bc30683588 Revert "app/internal/egl: accept zero EGLDisplay values as valid"
This reverts commit 66138e7890.

Reason: According to #77, it didn't work and the proposed fix
(retry when EGL_NO_DISPLAY is returned) is correct.

Elias Naur 66138e7890 app/internal/egl: accept zero EGLDisplay values as valid
Issue #77 seems to be caused by eglGetDisplay returning a zero
EGLDisplay, yet eglGetError returns EGL_SUCCESS. Since EGLDisplay
is not necessary a pointer type, the zero value may be valid.

Updates #77

Elias Naur 9b4176c475 app/internal/egl,app/internal/window: move Lock/Unlock methods
EGL contexts don't need locking, so their Lock and Unlock methods
are empty. Remove them and add them where necessary instead.

Elias Naur 8cec7d1a40 app/internal/window: move context refresh to window
Instead of calling from the low level context into the window
for its surface and dimensions, add a Context.MakeCurrent method
that does it directly.

The result is simpler and clearer logic. For example, synchronization
is obviously no longer needed. It wasn't necessary before, but the
reason was unclear.
