Creates the corresponding native graphics resources.
If there are already resources present due to an earlier create() with no corresponding destroy(), then destroy() is called implicitly first.
true
when successful, false
when a graphics operation failed. Regardless of the return value, calling destroy() is always safe. Implements QRhiTextureRenderTarget.

Releases (or requests deferred releasing of) the underlying native graphics resources.
Safe to call multiple times, subsequent invocations will be a no-op then.
Once destroy() is called, the QRhiResource instance can be reused, by calling create()
again. That will then result in creating new native graphics resources underneath.
The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
Implements QRhiResource.

The returned value is used in two ways: it can be passed to setRenderPassDescriptor() and QRhiGraphicsPipeline::setRenderPassDescriptor(). A render pass descriptor describes the attachments (color, depth/stencil) and the load/store behavior that can be affected by flags(). A QRhiGraphicsPipeline can only be used in combination with a render target that has a \l{QRhiRenderPassDescriptor::isCompatible()}{compatible} QRhiRenderPassDescriptor set.
Two QRhiTextureRenderTarget instances can share the same render pass descriptor as long as they have the same number and type of attachments. The associated QRhiTexture or QRhiRenderBuffer instances are not part of the render pass descriptor so those can differ in the two QRhiTextureRenderTarget instances.

Valid only after create() has been called successfully. Until then the result is a default-constructed QSize.
With QRhiTextureRenderTarget the returned size is the size of the associated attachments at the time of create(), in practice the size of the first color attachment, or the depth/stencil buffer if there are no color attachments. If the associated textures or renderbuffers are resized and rebuilt afterwards, then pixelSize() performs an implicit call to create() in order to rebuild the underlying data structures. This implicit check is similar to what QRhiCommandBuffer::beginPass() does, and ensures that the returned size is always up-to-date.
