Code Releases Activity

Update to glutin 0.17

Browse source 
Changes:

• Use the with_hardware_acceleration function on the ContextBuilder to not require the discrete GPU
• Remove the LMenu and RMenu virtual key codes (winit 0.16.0 removed these because Windows now generates LAlt and RAlt instead
• Replace set_cursor_state with hide_cursor (winit 0.16.0 removed the set_cursor_state function)
* Replace GlWindow::hidpi_factor with GlWindow::get_hidpi_factor and change to expecting an f64
* Use the glutin/winit dpi size and position types where possible

Notes:

The Resized event emitted by glutin carrys a logical/pixel size but I suspect that previously it was a physical/point size
Resizing the terminal, window and renderer all need physical/point sizes so a conversion needs to be made when handling
resized events
