-/**
- * Calculate the hardware instuctions to setup the current texture enviromnemt
- * settings. Since \c gl_texture_unit::_CurrentCombine is used, both
- * "classic" texture enviroments and GL_ARB_texture_env_combine type texture
- * environments are treated identically.
- *
- * \todo
- * This function should return \c GLboolean. When \c GL_FALSE is returned,
- * it means that an environment is selected that the hardware cannot do. This
- * is the way the Radeon and R200 drivers work.
- *
- * \todo
- * Looking at i830_3d_regs.h, it seems the i830 can do part of
- * GL_ATI_texture_env_combine3. It can handle using \c GL_ONE and
- * \c GL_ZERO as combine inputs (which the code already supports). It can
- * also handle the \c GL_MODULATE_ADD_ATI mode. Is it worth investigating
- * partial support for the extension?
- *
- * \todo
- * Some thought needs to be put into the way combiners work. The driver
- * treats the hardware as if there's a specific combine unit tied to each
- * texture unit. That's why there's the special case for a disabled texture
- * unit. That's not the way the hardware works. In reality, there are 4
- * texture units and four general instruction slots. Each instruction slot
- * can use any texture as an input. There's no need for this wierd "no-op"
- * stuff. If texture units 0 and 3 are enabled, the instructions to combine
- * them should be in slots 0 and 1, not 0 and 3 with two no-ops inbetween.
