Elias Naur abfbeb87cc gpu/internal/d3d11: stub BlitFramebuffer for D3D11 
The compute renderer doesn't run on Windows yet, but the d3d11 backend needs
the method to satisfy the driver interface.

Elias Naur 39775f555a gp/internal/opengl: support sRGB emulation for embedded content 
Programs such as gio-example/glfw rely on Gio drawing blending with
the framebuffer background. This change makes it so when sRGB emulation
is active.

Elias Naur 23e0c898ef gpu/internal/driver: use strings for generated DXIL assembly 
Literal strings are a more compact than literal byte slices. A future
change will switch to go:embed to save even more space.

Elias Naur fbee13a07d gpu/internal/convertshaders,gpu: represent converted shaders with raw literals 
Raw strings with linebreaks are easier to read and produce smaller
diffs.

Elias Naur c799452c57 gpu/internal/driver: rename gpu/backend 
There are no longer any importers of package backend outside of
gioui.org/gpu. Move it internally, and rename it to the slightly more
specific "driver" while we're at it.

Elias Naur 18a6dcf571 gpu/internal/d3d11: make the Direct3D backend internal to package gpu 
The package app/internal/d3d11 now contains only the GPU backend on
Direct3D. Move it below package gpu to reflect that.
