[Openexr-devel] Shade me confused

[Nafees Bin Zafar]

Hi Drew.  Looking through the ImageViewFragShader class, I see that the 
texel data passed into glTexImage2D() is just regular float data.  The 
internal format spec is set to GL_FLOAT_RGBA16_NV.  So where does the 
magic conversion to half type occur?

I am hoping that float data doesn't get transferred to the graphics card 
because that would transfer 16 unnecessary bits.
