871654c16f HDR: Better handling of the Sun 
Add transmittance to the Sun illuminance value to get correct colors at every time of day.
Also improved the Sun disk rendering.

a00f7ddfaf HDR: Fix Earth appearing to be "rounder" than normal 
We have to compensate for the fact that the sky-view LUT contains the view from the camera, but the skydome remains fixed on the ground.

af29642423 HDR: miscellaneous changes 
- Add an utility linearizeDepth function to help visualize the depth buffer for debug purposes.
- Use 'color0' instead of 'color' for all color attachments.
- Do not write to the HDR buffer if a fragment doesn't need shading (depth = 1).

d15b61e9b5 Reorganize the shadow mapping functions 
- Removed the multiple return statements, as they can be problematic with older GLSL 120 compilers
- Removed debug flags
- Moved code to separate functions for readability
- Reduced the band size to 0.1 to make more use of the higher quality cascades

8c01478ed8 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.

69387f09f4 Reduce shader complexity and implement graphics presets 
- All non-ALS Effects have been removed (except generic ones from model-default and terrain-default).
- The rendering dialog has been reworked to accomodate the changes.
- All necessary properties have been added to graphics-properties.xml
- Five graphics presets have been added: Minimal, Low, Medium, High and Ultra.
- Some unused properties have been removed from defaults.xml

textures to reduce tiling.

Also add a quality=1 technique which uses it.

fc27175690 Reduce shader attribute usage by packing floats 
Previously we required 6 shader attributes to pass
in all the required information for the building shader.
By using packing techniques this has been reduced to 4.

This should improve support for integrated graphics cards.
