Steps to reproduce the problem:
1. Run Chrome with the --force-gpu-mem-available-mb=5000 flag 
2. Load the attached file and click the run button to repeatedly create new textures

What is the expected behavior?
vram usage is allowed to get to 5000MB before the webgl context is lost

What went wrong?
The webgl context is lost when vram usage reaches 300MB

Did this work before? N/A 

Chrome version: 50.0.2661.102  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 21.0 r0

This is only reproducible running on the integrated graphics card below. The 300MB threshold does not apply when running on NVIDIA Quadro K1100M
