VK_KHR_dedicated_allocation, VK_KHR_buffer_device_address,
and VK_EXT_memory_budget can get used by VMA.
VK_KHR_spirv_1_4 can get used by the Shader.
VK_KHR_spirv_1_4 depends on VK_KHR_shader_float_controls.
VK_KHR_dedicated_allocation depends on VK_KHR_get_memory_requirements2
Setting the size of each descriptor pool to one
was a hack introduced to make the code work on android.
Changing the code to now allocate all descriptor sets at once
should fix the previous crash.
Not tested yet.
Before this patch, sometimes rendering a texture
on an android device would result in random things
appearing in the canvas, apart from the stuff
that has been drawn properly.
With these changes this does not seem to appear anymore.
It's not sure if this extension is supported everywhere
This commit uses normal descriptor pools, sets and writes,
which are all availabel in base vulkan.
Until now we only considered the builtin uniform variables.
This commit attempts to make the code in the vulkan Shader
implementation more general, as to allow for custom uniforms.
This is not possible yet, but should be easier to implement now.
There is no real effect yet when rendering, however debugging the
application with renderdoc reveals that the mipmap generation is
already correct. There's probably something weird going on with the
sampling. I'll have to look into that next.
There was a bug where the count of used builtin uniform buffer objects
was not advanced. This caused another problem since vulkan requires
a certain alignment for the buffer. This commit fixes both of those
things.
using the vulkan functionality probably leads to less bugs.
Until now it was assumed that any image was in the rgba8 format,
which is of course not correct. Clearing a texture to white or black
should now work for any format.
