51ed3aef63 Vertex and attribute compression to reduce the size of the vertex format. 
This allows Godot to automatically compress meshes to save a lot of bandwidth.

In general, this requires no interaction from the user and should result in
no noticable quality loss.

This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.

Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.

57eb762bae Add option to enable HDR rendering in 2D 
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance

Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.

intensity of specular contributed by this light source, but it was

possible to use in a custom light() shader.

f33ffd9ab4 Add Skeletons and Blend Shapes to the OpenGL renderer 
This uses a similar multipass approach to blend shapes
as Godot 3.x, the major difference here is that we
need to convert the normals and tangents to octahedral
for rendering.

Skeletons work the same as the Vulkan renderer except the bones
are stored in a texture as they were in 3.x.

385ee5c70b Implement Physical Light Units as an optional setting. 
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.

In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.
