2a9fd5ef13 mipmap: Avoid using the vertex backend when GopherJS is not used
The backend logic is especially for GopherJS. As the backend logic
tends to consume a lot of memory, let's avoid this when possible.

This is a preparation to remove source-region information from
vertices.

2a63512c6e driver: Add AddressUnsafe
This skips the source-region check and reduces 'if' branches from
shader programs.

AddressUnsafe is internal only so far. We might expose this value
later.

Fix another ~300 allocations per frame in my test project (#1089)
This simple change brings my simple test project from 752 allocations per frame to 474 allocations per frame. It seems a shame that go's escape analysis is not smart enough to leave this variable on the stack.

GeoM is a 24-byte struct and there is a slight perf difference that we are storing it in stack, but also copying it around with this change (instead of an 8-byte pointer). This could make things faster (due to stack / CPU cache) or slower (due to copying more memory) - when I try a stress test (drawing 100K images per frame), I can't see any actual performance difference (but I do see 100K fewer allocations, and GC is no longer running almost all the time).

graphicscommand: Return the error immediately (#1060)
Now grpahicscommand saves the error and shows the error after a
while. This was good to simplify the API but was the cause to hide
some issues.

This change fixes all the errors to be returned immediately, and
buffer this in the ebiten package instead.

c99fd1a742 mipmap: Create mipmap package and bufferd.Image uses it
Mipmap calculation must be executed after the main loop starts
because the graphics driver's HasHighPrecisionFloat is needed.
Then, operations on mipmap images must be called from images in
buffered package.
