rocket regions render solid white in p3tinydisplay

[Ed Swartz]

When the display is p3tinydisplay, rocket content renders solid white. (There's a directive for this at the top of main.py.)

This is happening on Linux on the recent git release/1.9 branch.

[Ed Swartz (eswartz)]

The reason for this is that textures for libRocket are not (usually) a power of two, and p3tinydisplay silently fails to load textures in this case. I think adding checks against Texture::getTexturesPowerOf2() and adjusting sizes would fix this.

[Ed Swartz (eswartz)]

BTW, I was adding code to log an error for the power-of-two case due to some confusion I had in the past, and code to adjust texture sizes in FilterManager.py for the same reason. I can see if the rocket render interface can be modified easily...

[Ed Swartz (eswartz)]

So, I was wrong -- the power-of-two textures was not the cause of the white rendering.

Simpler test case
