Improve API of color handling of text
...
Make the text color a rendering variable, so that it can be passed
through as uniform to the glyph shader and applied to the gray
map of the glyphs. This avoids re-creating the glyph runs when
merely the color changes.
This already "worked" for the glyph cache based text rendering,
but it wasn't used because of the wasm canvas code path. This
patch changes that to render the text into a text using simply black
and then render that texture using our existing glyph shader,
which merely uses the alpha channel anyway.
This reduces also #cfg's.

Improve RefCell usage

Use a RefCell only where we need it, in the glyph cache. We don't need
it for the platform data.

Fix GL texture not freeing its texture id
...
Similar to the shaders, keep a reference count on the resource itself and
keep the context around for convenient deletion.

Fix rendering of text with spaces

Don't waste glyphs and potential pixels from the rasterizer for space --
merely use the advance.
