Replaces the use of gl_generator with the glow wrapper:
* Add glow dependency, based on glow 0.6.1
* Pin version of glow fork for https://github.com/iceiix/glow/pull/1 until #442 renderbuffer
* Remove gl module, steven_gl
Porting details:
* Initialize glow in src/gl/mod.rs
* Call gl methods on glow context
* glow uses camelcase
* Import glow::HasContext trait, finds draw_elements etc.
* Fix mismatched types, glow uses Option and &str instead of raw pointers
* Fix uniform_location, glow already returns Some(u32)
* uniform_location: convert i32 to u32 for Uniform
* Fix attribute_location
* Fix shader creation Result u32 type
* Fix passing GLvoid and 2d/3d
* Fix missing Options type mismatches
* Offsets are i32 in glow, not GLvoid
* Fix clear_buffer using _f32_slice
* Delete methods are singular not plural
* glBufferData -> buffer_data_u8_slice
* buffer_sub_data_u8_slice
* Update more glow method wrapper names found by reviewing glow native platform
* Remove unused multi_draw_elements, can be replaced by draw_elements in a loop and it has no WebGL equivalent
* glow implements glMapBufferRange
* Remove unused read_buffer
* glow's deletes automatically pass 1 and take no reference
* shader_source() accepts &str directly; removes last of std::ptr
* Pass uniform Option<u32>
* Fix bool passing normalized parameter
* Fix draw_buffers parameter
* Stop unnecessarily returning context from gl::init
* Getting shader info is unsafe
* Unwrapping static mut is unsafe
* Use unsafe raw pointers for global mutable context
* Fix initializing GL objects wrappers from glow wrappers
* Unbinding framebuffers uses None
* Uppercase global to fix warning
* Shaders return Some instead of None
* Unbox the context to a raw pointer
* Use tex_image_2d_multisample added in glow fork
* Implement uniform_location, fixing unwrap None failed
* Add tex_sub_image_3d, using PixelUnpackData::Slice
* set_matrix4: transmute the Matrix4 since it is repr(C)
* get_pixels -> get_tex_image -> glGetTexImage, with PixelPackData::Slice
* Wrap sub_image_2d (glTexSubImage2D) and fix warnings
* Implement set_float_multi_raw and set_matrix4_multi, using from_raw_parts
Updating the glutin dependency to a 0.21.0-based branch, based on the migration guide at:
https://gentz.rocks/posts/glutin-v0-21-0-migration-guide/
* Remove glutin::ContextTrait
* Create window with ContextBuilder instead of WindowedContext::new
* Add .window() accessor on WindowContext, since it now dereferences to Context
In order to not break wasm32-unknown-unknown compilation, a minor fork is used of glutin v0.21.0 and a corresponding version of winit: https://github.com/iceiix/glutin/pull/1https://github.com/iceiix/winit/pull/2
- with stubs to compile (but not run, see issue #115)
* Add glutin dependency
* Create a glutin window
* Use the glutin window, basics work
* Store DPI factor on game object, update on Resized
* Use physical size for rendering only. Fixes UI scaled too small
Fixes https://github.com/iceiix/steven/pull/35#issuecomment-442683373

* Begin adding mouse input events
* Listen for DeviceEvents
* Call hover_at on mouse motion
* Listen for CursorMoved window event, hovering works
Glutin has separate WindowEvent::CursorMoved and
DeviceEvent::MouseMotion events, for absolute cursor and relative mouse
motion, respectively, instead of SDL's Event::MouseMotion for both.
* Use tuple pattern matching instead of nested if for MouseInput
* Implement left clicking
* Use grab_cursor() to capture the cursor
* Hide the cursor when grabbing
* Implement MouseWheel event
* Listen for keyboard input, escape key release
* Keyboard input: console toggling, glutin calls backquote 'grave'
* Implement fullscreen in glutin, updates https://github.com/iceiix/steven/pull/31
* Update settings for glutin VirtualKeyCode
* Keyboard controls (note: must clear conf.cfg to use correct bindings)
* Move DeviceEvent match arm up higher for clarity
* Remove SDL
* Pass physical dimensions to renderer tick so blit_framebuffer can use full size but the ui is still sized logically.
* Listen for DeviceEvent::Text
* Implement text input using ReceivedCharacter window event, works

* Request specific version of OpenGL, version 3.2
* Request OpenGL 3.2 but fallback to OpenGL ES 2.0 if available (not tested)
* Set core profile and depth 24-bits, stencil 0-bits
* Allow changing vsync, but require restarting (until https://github.com/tomaka/glutin/issues/693)
* Clarify specific Rust version requirement
* Import glutin::* in handle_window_event() to avoid overly repetitive code
* Linux in VM fix: manually calculate delta in MouseMotion
For the third issue on https://github.com/iceiix/steven/pull/35#issuecomment-443084458https://github.com/tomaka/glutin/issues/1084 MouseMotion event returns absolute instead of relative values, when running Linux in a VM
* Heuristic to detect absolute/relative MouseMotion from delta:(xrel, yrel); use a higher scaling factor
* Add clipboard pasting with clipboard crate instead of sdl2
