81fb4e7dfd Compositor: Add extra buffer formats 
These formats are not defined by OSG, so we manually define them. Some GPUs might not support them as we are using a GL compatibility context, but it shouldn't matter for now as they are only being used by the HDR pipeline.

65483a373f Shader-based scenery lights. 
This commit implements shader-based scenery lights with support for
efficient rendering of a large number of lights, animations and
directionality. Detailed commit log can be found at [1]. Detailed
discussions can be found on the mailing list [2][3][4].

578a8acff4 WS30: Improve tile loading times by ~50% 
Previously on my system, generating vegetation for a given tile
took 0.15-0.2s (for ~ 56k positions), of ~0.4s.  While this is done in a
separate loading thread, the sheer number of tiles being loaded
caused noticeable delays and popping of higher LoD tiles.

As a tile at the highest LoD is typically 6x6km, and vegetation
is generated on a scanline of individual triangles, there is a _lot_
of temporal locality on the landclass of a series of points.

By caching the material information required from the landclass lookup
we can avoid a whole much of material lookups for each successive
vegetation point.

On my system this reduced the time to generate vegetation down to
0.02s per tile, and total tile generation time down to ~0.2s.

d1e9134a89 WS30: Improved vegetation constraints 
Unlike the elevation constraints, the vegetation constraints
don't need to be global.  So no need for mutexes.  Big speed up.

95239fea87 simgear/io/iostreams/zlibstream.*: improved support for reading compressed data. 
Added support for seeking (forwards only) - in ZlibAbstractIStreambuf, added
seekoff().

Also disabled assert that checked that we reach EOF compressed data at same
time as EOF uncompressed data; was breaking things when using embedded
compressed streams within fgtape recording.

Added ZLibCompressionFormat::ZLIB_RAW, uses windowBits=-15, for zlib compressed
streams without header or trailer.

Fixed clang build error with std::min().

b3b863a3c4 Preliminary changes for the HDR pipeline 
- Add an Effect to stars and planets so they don't disappear when not using the fixed-pipeline.
- Allow usage of the shadow mapping related uniforms in 'quad' passes as well.
- Add extra buffer formats (some of them only work under the core profile).
- Better handling of mipmapping in the Compositor.
