This is a refactoring change to prepare for another gpu.Backend
implementations.
Notably, app/loop.go no longer imports gpu/gl.

The rendering implementation is needed for using Gio UI with external
window libraries such as GLFW. Expose it in the new package gpu.

We'd like to support Gio using a different renderer binding than
the builtin. A first step is to define the Functions interface
in package gl, and extract the concrete implementations to a
separate package.

Before this change, Gio tries hard to come up with a reasonable UI scale
factor on desktop OSes derived from the physical dimensions and
resolution of connected monitors. Gio also attempts to detect the user
specified system UI scale and apply it.
However, all that is complex and misguided:
- The UI scale should not depend on whatever monitor is connected at
program startup - For multiple monitors, it's unclear which one to base
the scale off. - Applying both a monitor derived scale *and* the user
specified scale is wrong, because the user scale is relative to some
fixed scale, not Gio's derived scale. - With an automatic scale, Gio
does not respect user preference and will not have a similar scale to
other programs on the desktop.
Get rid of the the automatic UI scale detection and rely only on the
user scale.

To keep text legible on low DPI monitors, the number of pixels
per dp or sp is not is not allowed to go below minDensity. However,
a minimum density of 1.25 leads to too big text and widgets on a
baseline ~96 DPI monitor. Lower the minimum to 1.0, where text is still
legible.
