Is Floating Point Texture Support Enabled in Mesa?

I am attempting to play a game through CrossOver for Linux. However, I get a warning that floating-point textures isn't supported in OpenGL. I recently found that this was due to a legal issue that has since been resolved.

Is there a way to enable floating-point texture support in the Mesa driver from the Ubuntu repositories? Or am I required to compile an updated driver with the needed features enabled?

If you have not already done so:

Install the latest drivers from oibaf/ppa

sudo apt-add-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade

to check for the floating-point textures:

glxinfo | grep -i texture_float

If you get some output, you may assume that it is present.
