84e53d4c61 internal/graphicsdriver/opengl, internal/uidriver/glfw: treat Win32 API errors correctly 
The returned errors from syscall.Syscall* and windows.LazyProc.Call come
from GetLastError. The value of GetLastError is not reliable when the
function succeeds.

This change fixes the usages of error values. The error value is now
used only when the API explicitly fails.

1799ed0b28 add a build tag 'ebitencbackend' and internal/cbackend 
This enables to create a C archive with Ebiten without an actual driver
implementation. This enables Ebiten work on a platform Go doesn't support.
See also Hitsumabushi project: github.com/hajimehoshi/hitsumabushi.

The backend C API is not stable and might change later. Then, the build
tag 'ebitencbackend' is not documented on purpose.

Closes #1900
