* renderer_gl: Make rasterizer normal class member * It doesn't need to be heap allocated anymore * gl_rasterizer: Remove default_texture * It's unused * gl_rasterizer: General cleanup * gl_rasterizer: Lower case lambdas * Match style with review comments from vulkan backend * rasterizer_cache: Prevent memory leak * Since the switch from shared_ptr these surfaces were no longer being destroyed properly. Use our garbage collector for that purpose to destroy it safely for both backends * rasterizer_cache: Make temp copy of old surface * The custom surface would override the memory region of the old region resulting in garbage data, this ensures the custom surface is constructed correctly * citra_qt: Manually create dialog tabs * Allows for custom constructors which is very useful. While at it, global state is now eliminated from configuration * citra_qt: Eliminate global system usage * core: Remove global system usage in memory and HIO * citra_qt: Use qOverload * tests: Run clang format * gl_texture_runtime: Fix surface scaling
