LibretroGLCoreContext is the backend for RETRO_HW_CONTEXT_OPENGL_CORE,
so the frontend hands us a desktop GL Core profile context. But
CreateDrawContext() never told GLFeatures about it — useCoreContext
stayed at its default false and gl_extensions.IsCoreContext stayed
false, so the macOS Core-profile workaround at GLFeatures.cpp:532
(which force-enables ARB_framebuffer_object because Apple's Core
driver doesn't list it as an extension) never fired.
Every glBindFramebuffer(GL_FRAMEBUFFER, g_defaultFBO) in
GLQueueRunner::fbo_unbind then fell through both branches and silently
no-op'd, so the BackBuffer present pass rendered into nothing and
GL_INVALID_OPERATION accumulated. End result: black screen on macOS,
audio and game logic still working.
One-line fix: call SetGLCoreContext(true) before CheckGLExtensions().
* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
