Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.

Setting the GLESv2 parameter GL_PACK_ALIGNMENT to 1 ensures that the
stride of the glReadPixels output matches the value computed in
`pack_stride`. Since the default value of GL_PACK_ALIGNMENT is 4, this
does not make a difference under normal use; but without this patch
the stride can be incorrect; for example, with RGB565 buffers and
screenshots of regions with odd width.
We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
Reverts commit c73e20628a.
This caused a regression in the GLES2 renderer because `egl->exts.EXT_device_drm` is set in
`egl_init_display()`, which is invoked after `get_egl_device_from_drm_fd()`. So the function will
always return `EGL_NO_DEVICE_EXT`.
Some formats like YUV are only supported by Mesa for sampling, not
for rendering. However we always unconditionally added the INVALID
modifier to the list of render formats.
Check whether all modifiers are external-only, in that case, don't
add INVALID to the list of render formats.
The Vulkan spec doesn't guarantee that the driver will wait for
implicitly synchronized client buffers before texturing from them.
radv happens to perform the wait, but anv doesn't.
Fix this by extracting implicit fences from DMA-BUFs, importing
them into Vulkan as a VkSemaphore objects, and make the render pass
wait on these VkSemaphores.
pre_cb was an alias for stage_cb->vk. Let's just use a single
variable instead.
Additionally, early return when vulkan_record_stage_cb() fails.
We were crashing in vkCmdPipelineBarrier() if that happened.
Skip clears with an empty scissor.
Fixes the following validation error:
00:00:09.734 [wlr] [render/vulkan/vulkan.c:61] Validation Error: [ VUID-vkCmdClearAttachments-rect-02682 ] Object 0: handle = 0x62600001b100, type = VK_OBJECT_TYPE_COMMAND_BUFFER; | MessageID = 0xadbd476f | CmdClearAttachments(): pRects[0].rect.extent.width is zero. The Vulkan spec states: The rect member of each element of pRects must have an extent.width greater than 0 (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdClearAttachments-rect-02682) (VUID-vkCmdClearAttachments-rect-02682)
We were filling VkTimelineSemaphoreSubmitInfoKHR.pSignalSemaphoreValues,
but we were missing VkSubmitInfo.pSignalSemaphores.
This was causing VkTimelineSemaphoreSubmitInfoKHR.pSignalSemaphoreValues
to be ignored. By chance, the render command buffer was using the
next timeline point, so we were waiting for that instead.
struct wlr_vk_format_props contains a mix of properties for shm
and dmabuf, and it's not immediately clear which fields are for
which kind of buffer. Use a nested struct to group the fields.
