When we remove the background from a glyph, we can keep track of if we
made all the pixels fully transparent. If we did, we can just skip
future calls to _drawFromCache, since it would be a noop anyways.
This adds a very minimal implementation of DynamicCharAtlas using a LRU
cache.
I've got some optimizations that I'll add on top of this, but this
proves the concept.
This adds the logic needed to switch between multiple char atlas
implementations, and an example second implementation to test it out
with.
This also offers an escape hatch if something goes wrong with the char
atlas implementation(s).
The API defined by BaseCharAtlas will let us support multiple char atlas
implementations at once.
I tested this by running the demo with Chrome's profiler, which shows
that calls are going to StaticCharAtlas/drawImage instead of
_drawUncachedChar. Applications using 256 colors also still work fine,
via _drawUncachedChar.
I have added blob handler for the attach Addon.
This allows to handle Docker with ws (works on Docker API v1.35)
I have also added a callback to handle asynchronous FileReader.
This mostly worked before, but clearColor made the assumption that the
colors were always in #RRBBGG format. See the discussion here:
https://github.com/xtermjs/xterm.js/pull/1327#issuecomment-374812842
This changes the internal representation of a color so that we hold onto
into an object containing the original css string along with an RGBA
value encoded as a 32-bit uint. clearColor can then use that RGBA
representation.
Additionally, this deduplicates some code between ColorManager and
Terminal. Terminal was generating the 256 ansi colors the same way
ColorManager was, so this just makes Terminal use the same constant.
Selected inline-styles were externalized to xterm.css.
The `Terminal._charSizeStyleElement` is removed since it
was not used anymore.
