Windows DLLs missing functions.

[ryhor-spivak]

In v0.7.0.2 some functions are missing in dll/lib, for example wgpuQueueWriteTexture, wgpuBufferDestroy and wgpuTextureDestroy.

There are wgpu_buffer_destroy and wgpu_texture_destroy in dll exports, along with some others snake_case names from previous versions like wgpu_render_pass_draw, wgpu_render_pass_draw_indexed. But there is no header for them.

This is due the fact that the code is now generated from the webgpu headers (instead of the other way around). Not sure what the implications for the missing destroy functions are, but I assume the resources are cleaned up automatically. I think gpuQueueWriteTexture is still there, is it not?

Here is a full list of exported functions.

For queue there are only wgpuQueueSubmit and wgpuQueueWriteBuffer. wgpuQueueOnSubmittedWorkDone and wgpuQueueWriteTexture are missing.

It appears those functions haven't been ported since #85

wgpuQueueSubmit and wgpuQueueWriteBuffer are defined here:

wgpu-native/src/device.rs

Lines 287 to 309 in b405590

	#[no_mangle]
	pub unsafe extern "C" fn wgpuQueueSubmit(
	queue: id::QueueId,
	command_count: u32,
	command_buffers: *const id::CommandBufferId,
	) {
	let command_buffer_ids = make_slice(command_buffers, command_count as usize);
	gfx_select!(queue => GLOBAL.queue_submit(queue, command_buffer_ids))
	.expect("Unable to submit queue")
	}
	#[no_mangle]
	pub unsafe extern "C" fn wgpuQueueWriteBuffer(
	queue: id::QueueId,
	buffer: id::BufferId,
	buffer_offset: u64,
	data: *const u8, // TODO: Check - this might not follow the header
	data_size: usize,
	) {
	let slice = make_slice(data, data_size);
	gfx_select!(queue => GLOBAL.queue_write_buffer(queue, buffer, buffer_offset, slice))
	.expect("Unable to write buffer")
	}

Several functions were added back in #95 and #96. These include all functions mentioned in the comments above except wgpuQueueOnSubmittedWorkDone.

#246 somewhat fixed this, now all functions present in the headers should be exported by the lib.
But still some functions are unimplemented & they will cause a panic on call.
All of them are listed in unimplemented.rs:

wgpu-native/src/unimplemented.rs

Line 1 in 6f95ce3

use crate::native;

So I think we should have a separate issues for implementing each of those functions, or group of similar functions.
Closing this in favor of that.
