Allow length of the light direction vector to influence strength of the light source.
...
This fixes the issue with objects and terrain being darker than they should be. As it turns out, most levels have not normalized light direction which happens to make light brighter and this is the expected result. To keep in line with GL14 engine, newer engines should use the length of the vector to make light brighter.

It's unused, and it's a bad idea - it's important for authoring tools

dynamically created.

Don't create a color renderbuffer for shadow map
...
When rendering the shadow map offscreen using framebuffer objects, it's
not necessary to create a color renderbuffer. Currently
FramebufferParams only lets you choose between a renderbuffer and a
texture for both color and depth attachments. This changes that, and now
you can ask for a texture, a renderbuffer, or nothing.
This improves performance. On my computer, with an 8192x8192 shadow map,
this improves overall frame time by 8.0%.

Improve shadow quality and performance in gl33
...
If CONFIG_QUALITY_SHADOWS is defined (which it always is) then the
fragment shader code that samples the shadow map will take five samples
in a cross shape around the point to be sampled, to apply antialiasing.
Currently, the offset of these samples is hardcoded to 0.00025× the
shadow map resolution. This is very inconsistent: if the shadow map
resolution is 128×128, then these samples are 0.032 texels apart, which
is a waste of four texture samples, and essentially means that no
antialiasing is applied. If the shadow map resolution is 8192×8192, then
these samples are 2.048 texels apart, which causes visual artefacts
around shadow edges, instead of giving smoother shadows.
The correct thing to do is to always sample exactly one texel away from
the original position. This is easy in GLSL 3.30, as it includes a
textureOffset function which offsets a texture fetch by an exact number
of texels. This is faster than manually calculating an offset ourselves,
it fixes visual artefacts at high resolutions, and it properly applies
antialiasing at low resolutions.
