Use an arena allocator in ShaderModelRenderer::Render, to reduce
the allocation cost in STL containers.
Avoid unnecessary copying of std::vectors.
This was SVN commit r13911.
Switch all the constant strings in graphics code to use the new
variables.
This avoids the cost of instantiating CStrInterns at runtime every
frame.
This was SVN commit r13906.
CShaderDefines is designed to be efficient to copy and compare, but not
to construct. Conditional defines were constructing new CShaderDefines
for many models every frame.
Precompute all the possible conditional combinations of CShaderDefines
when a material is first loaded, so they can be looked up at no cost
when rendering.
This was SVN commit r13902.
Support conditional expressions in shader effect XML files.
Consolidate fixed-function model rendering into the shader system.
Remove lots of now-obsolete renderer code.
Move shader defines from std::map to new class with interned data, for
performance.
Move texture from model into material.
Alleviate singletonitis.
Remove obsolete lodbias setting.
Remove unused terrain shadow transparency.
This was SVN commit r11423.
Change lighting model for new maps to allow better overbrightness.
Cache player colours instead of loading from scripts every time the
renderer wants them.
This was SVN commit r9123.
