- moved gl_spritelight out of gl/. This required a few more changes:

Browse source 
* split gl_shadowmap.cpp into a GL dependent and an API independent part.
* gl_drawinfo must be kept around for the HUD sprite because it connects the renderer with the hardware indpendent part of the engine.

/*
The 1D shadow maps are stored in a 1024x1024 texture as float depth values (R32F).
Each line in the texture is assigned to a single light. For example, to grab depth values for light 20
the fragment shader (main.fp) needs to sample from row 20. That is, the V texture coordinate needs
to be 20.5/1024.
The texel row for each light is split into four parts. One for each direction, like a cube texture,
but then only in 2D where this reduces itself to a square. When main.fp samples from the shadow map
it first decides in which direction the fragment is (relative to the light), like cubemap sampling does
for 3D, but once again just for the 2D case.
Texels 0-255 is Y positive, 256-511 is X positive, 512-767 is Y negative and 768-1023 is X negative.
Generating the shadow map itself is done by FShadowMap::Update(). The shadow map texture's FBO is
bound and then a screen quad is drawn to make a fragment shader cover all texels. For each fragment
it shoots a ray and collects the distance to what it hit.
The shadowmap.fp shader knows which light and texel it is processing by mapping gl_FragCoord.y back
to the light index, and it knows which direction to ray trace by looking at gl_FragCoord.x. For
example, if gl_FragCoord.y is 20.5, then it knows its processing light 20, and if gl_FragCoord.x is
127.5, then it knows we are shooting straight ahead for the Y positive direction.
Ray testing is done by uploading two GPU storage buffers - one holding AABB tree nodes, and one with
the line segments at the leaf nodes of the tree. The fragment shader then performs a test same way
as on the CPU, except everything uses indexes as pointers are not allowed in GLSL.
