kitty now supports the SGR DIM escape code, which makes text fade into
the background. It works by alpha blending the text color into the
background color. Fixes #446

Get background_opacity working, at the cost of breaking negative z-index image rendering.
...
Image rendering will need to use an FBO since OpenGL cannot do proper alpha compositing.
As a first step, the interleaved shaders now generate premultiplied colors as opengl can only alpha blend pre-multipled colors

Workaround to get graphics working on Apple's buggy products
...
Apparently some macOS OpenGL drivers cannot handle using a VAO with
attributes that have different divisors/apply to different shaders. So
use a separate VAO for graphics rendering. This is a small performance hit,
but is the price of supporting substandard computers.

Switch to using an opaque block cursor

The text is rendered in the background color on top of the opaque
block cursor. We use the background color since applications can change
both cursor and background colors, so it is up to the application to
ensure the colors have good contrast. Fix #126

Move the text attributes out of the char type
...
This means that more text attributes can be added in the future (there
are 8 bits available) and there is no need to keep bit twiddling when
accessing the chars themselves. Also means less data needs to be sent to
the GPU. Cell size does not change since there were currently 2 unused
bytes because of alignment.
