Preparation for text handling
...
Ensure the dpi on the canvas is up-to-date before/after rendering, as
measure_text etc. rely on it and it's otherwise initialized to 1 by
default. Unfortunately this requires jumping through some hoops, but
that can be fixed later in the canvas.

Implement releasing of textures when items are destroyed
...
This means going back to an immutable renderer reference and interior
mutability for the canvas and the gpu cache. This is because while
traversing the item tree for rendering we may end up destroying
other items due to the lazyness of the models.

Rename the image cache

... to a more general gpu_cache and store an enum. That way we can
encapsulate the resource releasing - in the future - entirely in the
backend through run-time polymorphism in the backend (gpu cache data
enum) instead of a vtable method in the item to destruct the correct
type of data.

Fix color blending when using the alpha channel

Given choice of ONE_MINUS_SRC_ALPHA blending function, we assume not
only that textures are pre-multiplied with their alpha (see commit
bf396ad578
), the same applies also to
flat colors.
This fixes blending such as this:
App := Window {
Text {
text: "Hello World";
}
Rectangle {
color: #ff335588;
width: 100%;
height: 100%;
}
