vulkan: Drop GskVulkanPipelineLayout We already move the descriptor set layout out of it, so we can just as well keep the pipeline layouts in the render object as well, and get rid of this extra object. Update all callers. 2017-09-22 17:30:26 +00:00			`GskVulkanPipeline * gsk_vulkan_blur_pipeline_new (GdkVulkanContext *context,`

Clip intermediate textures In some cases, we were creating gigantic intermediate textures only to clip out a small section afterwards (e.g. in the listbox example in gtk4-demo). This is wasteful if we apply effects on the texture, such as blur or color-matrix. So, clip the dimensions of the intermediate texture with the current clip. To make this feasible, we move the texture coordinate computation out of the pipeline setup functions into the node_as_texture function where this clipping happens. One extra complication we encounter is that the node might get clipped away completely. Since Vulkan does not allow to create empty images, we bail out in this case and not draw anything. With these changes, the listbox example in gtk4-demo goes from 32M pixels of intermediate texture to 320000. 2017-10-01 23:17:39 +00:00			`const graphene_rect_t *tex_rect,`
