Update gfx_device_gl dependency

[smolck]

Hello! After trying to run the example given here on the main Piston repo using piston_window version 0.103.0 (I believe the same happens on v0.98.0, but would need to verify), I got two errors when compiling gfx_device_gl (on latest nightly) that looked a bit like this:

failed to resolve: could not find `format args` in `core`

Upon further investigation, it appears to be a bug in gfx_device_gl version 0.16.1 (and apparently older versions since AFAIK piston_window version 0.103.0 uses gfx_device_gl version 0.15.0, right?). The issue on gfx_device_gl is here:
gfx-rs/gfx#2964

The bug is fixed in gfx_device_gl version 0.16.2. Would it be feasible to upgrade piston_window's dependency on gfx_device_gl to version 0.16.2 to fix this? If not, is there another way to fix this?

Thanks!

This is done automatically by cargo update.

I’m speaking of the dependency here in Cargo.toml. cargo update doesn’t change the Cargo.toml file (at least for me). Should it?

I have the same problem. Is this going to be updated?

Todo:

• Update "piston-gfx_texture"
• Update "piston2d-gfx_graphics"
• Update "piston_window"
