Fixed FOV side effect on light sprite size.
...
The light sprite diminished to zero size as the FOV was decreased
(in sim zoom), and increased considerably as the FOV was increased.
This commit fixed this by taking the FOV into account to keep the light
sprite size roughly constant across the valid FOV range.

HDR: Optimize the G-Buffer and do not separate the occlusion texture
...
- The G-Buffer layout has been redesigned to be 96 bits per pixel. There are 24
unused bits that can be used for extra material parameters later (like
clearcoat).
- Add better debug views for the G-Buffer.
- Use octahedron normal encoding. This yields the same results as the previous
method but uses 16 bits less.
- Use rg11fb10f for the environment mapping cubemaps.
- Tweak the shadow mapping parameters and add a colored debug mode.
- Only render shadow maps for objects that inherit from model-default.eff or
model-pbr.eff instead of having a fallback Effect. Now transparent objects
should be ignored (if they are marked as such with model-transparent or
similar).
- Remove the separate occlusion texture. Now the PBR Effect expects a single
texture where R=occlusion, G=roughness and B=metallic.

It's now possible to create a overrides of water colour and shallowness for waterbodies through regional definitions. Note: Overrides are constant and apply throughout the waterbody. This is mainly useful for inland waterbodies.
...
- Added overrides as parameter values for: water floor_colour (vec3 RBG colours. Range: 0 to 1. Defaults: old inland map colour, a blue ocean colour.), water_shallowness (Same as depth map texture. Range: 0 to 1. Defaults: 1.0 inland, 0.7 ocean). The corresponding texture lookup branches are also gated by these uniform flags for performance reasons.
