[Bf-committers] RE: Floats and dispview?

[Salvatore Russo]

Hi,

For the pixel drawing, I only use texture drawing. But with
what you said Ton, these floats should not be a big problem
anymore in the near future so I will wait.

Concerning the rendering, I will give a better look on all the
new functionalities and follow your suggestions.

Thanks for your answer,
Salvatore
