Previously there was already "draw_shape" property,
but it was doing nothing. This commit renames the
property to "display_shape". Furthermore, different
shapes like SQUARE and DIAMOND are supported now.
Currently, the shapes are drawn using the shader that also
draws keyframes. In the future we might want to separate
this.
The new shapes are not used anywhere yet, but they can
be used by addon developers and will probably be useful
when we want to support different kinds node systems later.
For example, different shapes can be used to distinguish
between data and control flow.

With the new automatic handle algorithm, it is possible to do a lot
of the animation via keyframes without touching the curves. It is
however necessary to change the keyframe interpolation and handle
types in certain cases. Currently the dopesheet/action editor
allows changing the types, but does not show them in any way.
To fix, add a new menu option to display this information. For handle
type, it is represented using the shape of the key icons: diamond for
Free, clipped diamond for Aligned, square for Vector, circle for Auto
Clamp, and cirle with dot for Automatic.
Non-bezier interpolation is a property of intervals between keys,
so it is marked by drawing lines, similar to holds. In this initial
version, only the fact of non-bezier interpolation is displayed,
without distinguishing types. For summaries, the line is drawn at
half alpha if not all curves in the group are non-bezier.
In addition, it is sometimes helpful to know the general direction
of change of the curve, and which keys are extremes. This commit
also adds an option to highlight extremes, based on comparing the
keyed values with adjacent keys. Half-intensity display is used
for overshot bezier extremes, or non-uniform summaries.

* Outlines of keyframes were too thick and ugly
* Size differences between keyframe types was being swallowed
by the pixel-fudge factor, leaving colour as the only distinguishing
factor (bad!)
- Size parameter is total size of the shape, not its radius (half size). Updated hard-coded sizes to match this.
- Shader expands size to include outline.
- Fixed fringe between outline color and transparent background.
Now we can draw keyframe markers as point sprites, with fewer draw calls and state changes.
Based on the builtin shader for round points with anti-aliased outline. This one is more pointy.
