4c640d2500 buffered, restorable: Remove copying pixels 
Instead, the callers (ebiten.NewImageFromImage and
(*ebiten.Image).ReplacePixels) have responsibility to copy the
pixels now. This change should reduce unnecessary copying pixels.

d9cf1095d4 buffered: Bug fix: Race conndition on delayedCommands 
This CL fixes the race condtion on delayedCommands, which can be
accessed and set to nil at the same time.

This CL separates some operations for delayedCommands into slow-
paths and fast-paths, and use mutex only at slow-paths for
performance. The implementation is based on sync.Once.

620981a09a ebiten: Make ebiten.Image and buffered.Image 1:1 
This change creates a new buffered.Image even for a sub-image. This
can increase a memory usage a little, but decrease the GPU memory
usage since only the necessary pixels are allocated on a texture
atlas.

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).
