Update the OpenGL backend

ef0c0e0679
Associate texture parameters in shaders with specific texture units, to work
...
around a macOS Radeon driver bug.
Also, ensure there is always a dummy texture bound to every parameter in the
OpenGL backend.
These together stop the macOS Radeon drivers from recompiling the shader on
every drawcall.
Possibly addresses #300 .

Add a compute shader path, optimize GPU memory management, and switch from SDL
...
to `surfman`.
This is a large commit; explanations of each change follow.
This adds an optional compute shader path, off by default, for rendering fills
to alpha masks. It usually does not improve performance at present, but it
provides a good baseline for further optimizations. Later improvements will
likely aim to avoid writes to the mask texture entirely. Supporting
infrastructure for compute shader has been added to `pathfinder_gpu` for the
OpenGL and Metal backends.
The Metal backend has been optimized to avoid unneccessary buffer allocations
and reflection. As part of this, argument buffers have been removed, as the
current SPIRV-Cross compiler no longer requires them.
The GPU renderer has been improved to avoid stalls. Now, separate buffers are
allocated for each fill batch and for each frame. This can be extended in the
future to allow for separate buffers for tile draw operations as well.
SDL usage has been removed in favor of the native Rust `surfman` and `winit`.
Because `surfman` allows for selection of the integrated GPU on multi-GPU
system, it is chosen by default. The demo supports a new
`--high-performance-gpu` option to opt into the discrete GPU.

These cannot be implemented with the standard OpenGL blending functions, so we

Add Metal support.
...
This commit substantially reworks the `pathfinder_gpu` API to better support
modern APIs like Metal. It should open the door to `gfx-rs`, `wgpu`, Vulkan,
and D3D12 backends relatively straightforwardly.
A new example, `canvas_metal_minimal`, has been added.
Note that the new Metal shaders require a patched version of `spirv-cross` to
build properly. An upstream patch is forthcoming.
