RZAPIRenderer::DrawIndexed doesn't work with ImGuiRenderer uses wrong scissor rect

[Pikachuxxxx]

RZAPIRenderer::DrawIndexed() is not able to use the Scissor rect set throught RZAPIRenderer or RZCommandBuffer (I've personally tried both the design changes) both vkCmdSetScissor and vkCmdDrawIndexed need to be set simultaneously in the same scope for it to work. The reason is that scissor rect is not properly set before the draw call for indexed rendering, it's losing that information.

 for (uint32_t i = 0; i < imDrawData->CmdListsCount; ++i) {
                const ImDrawList* cmd_list = imDrawData->CmdLists[i];
                for (int32_t j = 0; j < cmd_list->CmdBuffer.Size; j++) {
                    const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[j];
                    RZDescriptorSet* set = (RZDescriptorSet*) pcmd->TextureId;
                    RZAPIRenderer::BindDescriptorSets(m_ImGuiPipeline, cmdBuffer, &set, 1);
                    // Fix this for Vulkan
                  
                    RZAPIRenderer::SetScissorRect(cmdBuffer, std::max((int32_t) (pcmd->ClipRect.x), 0), std::max((int32_t) (pcmd->ClipRect.y), 0), (uint32_t) (pcmd->ClipRect.z - pcmd->ClipRect.x), (uint32_t) (pcmd->ClipRect.w - pcmd->ClipRect.y));
                    vkCmdDrawIndexed(*cmdBuf, pcmd->ElemCount, 1, indexOffset, vertexOffset, 0);
                    //RZAPIRenderer::DrawIndexed(cmdBuffer, pcmd->ElemCount, 1, indexOffset, vertexOffset, 0);
                    indexOffset += pcmd->ElemCount;
                }
                vertexOffset += cmd_list->VtxBuffer.Size;
            }

ImGui only work if RZAPIRenderer::DrawIndexed is not used

RZAPIRenderer::DrawIndexed Doesn't work with ImGui Renderer

Workaround : I don't mind putting such hacky stuff in here, I don't want to be a bitch about making everything super decoupled, use macros and GetRenderAPI to make this work, this doesn't affect the performance at all. Hence this is OK!

Will be investigated by ME only it's a major problem when dealing with multi-viewport rendering.

Until then, If anyone want to solve this I will give you 69 jelly beans as a gift. Free shipping to anywhere in the world.
