eeb5687b73 internal/graphicsdriver/metal, internal/graphicsdriver/opengl: change the return type to pointers 
On second thought, returning pointers is more natural. Handling

7bb7e45522 internal/graphicsdriver/metal, internal/graphicsdriver/opengl: change the return type to interface 
Converting a nil with a pointer type to an interface type is no longer
a nil-nil interface, and then comparing with nil causes an unexpected
results.

566957dc1c internal/graphicsdriver/metal: invert Y at the vertex shader 
Instead of using a negative height in the viewport, invert the Y direction
at the vertex shader. This is a little more readable as a negative height
is hacky.

This is a preparation for DirectX 12. DirectX 12's coodination system
is very similar to Metal, but doesn't treat a negative height in its
viewport unfortunately.

internal/atlas: optimization: send premultiplied alpha from vertex to fragment shader. (#1996) 
Note that this applies only to the builtin shaders - interface for Kage stays
unchanged for compatibility.

Minor compatibility delta: when interpolating alpha values, previous code has
created nonsense values, such as, when interpolating from
fully-transparent-black (0,0,0,0) to opaque-white (1,1,1,1), something like
half-transparent-grey (0.25,0.25,0.25,0.5) where half-transparent-white
(0.5,0.5,0.5,0.5) is used by the new code.

I assume this is a strict improvement, however this may warrant some testing.

Possible later improvement could be moving the premultiplication from fragment
shader to CPU. Did not do this as it makes the code rather inconsistent of Kage
vs built-in shader usage.

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.
