Update canvas_nanovg example
The `canvas_nanovg` example would not run on my Linux machine due to the bug in `winit` 0.19 (rust-windowing/winit#1773)
In this PR, I updated `winit` and `surfman` and made the minimum necessary changes so that the example would compile and run.

Make `canvas_minimal` example rerender on refresh
I'm not sure if this actually works, because the `canvas_minimal` example doesn't run on my computer.
eliminates double layouts.
This adds an extension to the HTML canvas API that allows you to pass the
`TextMetrics` object returned by `measure_text()` to `fill_text()` and/or
`stroke_text()` to draw the measured text without laying it out again. It
improves performance on the `canvas_nanovg` demo.
Before this change, the `canvas_text` example would become blank after
navigating to another workspace or being put beneath another window.
This change will listen for the SDL window exposed event, and will
render then instead of only at the beginning.
and `macos_app` examples.
`winit` does not create an autorelease pool, so the Metal backend had not taken
the presence of one into account. Now the Metal backend creates and flushes
autorelease pools as necessary.
Closes#334.
Closes#376.
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.
We can do more tile-based optimization, but this should be enough to ensure a
correct rendering.
This temporarily breaks subpixel AA, but it should be fixable by modifying
`blur.fs.glsl`.
Closes#271.
These cannot be implemented with the standard OpenGL blending functions, so we
have to do them manually in a shader, which requires a good deal of machinery
to create intermediate framebuffers and so forth.
