<ul>
<li>Shading language programs are compiled into low-level programs
very similar to those of GL_ARB_vertex/fragment_program.
<li>All float/int/bool and vector types currently occupy full
<li>All vector types (vec2, vec3, vec4, bvec2, etc) currently occupy full
float[4] registers.
<li>Float constants are packed so that up to four floats can occupy one
program parameter/register.
<li>Float constants and variables are packed so that up to four floats
can occupy one program parameter/register.
<li>All function calls are inlined.
<li>Shaders which use too many registers will not compile.
<li>The quality of generated code is pretty good, register usage is fair.

<h2>Programming Hints</h2>
<ul>
<li>Always declare <em>in</em> function parameters as <em>const</em>.
<li>Declare <em>in</em> function parameters as <em>const</em> whenever possible.
This improves the efficiency of function inlining.
