bbeb0d14e6 buffered: Defer filling an image
This change defers filling an image so that successive fillings
can be merged into one for more efficient rendering.

1d701577d6 buffered: Use the pending pixels when possible at At
(*Image).At can be unnecessarily slow since this tries to get
pixels from GPU. This change reduces the chance to read GPU by
using its pending pixels when possible.

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.

3cf867035d buffered: Do not delay commands if possible
Delaying commands causes memory allocations, which can be heavy
especially on browsers.

This avoids to use 'defer' for performance.
