* win32 backend * [rcore][win32] use SwapBuffers instead of wglSwapLayerBuffers I don't understand OpenGL well enough to know the difference between SwapBuffers and wglSwapLayerBuffers but the former seems to double my FPS (from 2000 to about 4000 in core_vr_simulator). * [rcore][win32] stop lying to the OS about when our window is updated Instead of calling BeginPaint/EndPaint in WM_PAINT which signals to the OS that our window content is updated, now when we encounter the WM_PAINT message instead we return back to the raylib application which will trigger it to render a new frame. We've replaced the call to BeginPaint and EndPaint with a call to ValidateRect in SwapBuffers, which, means we're now correctly telling the OS when our window content is actually up-to-date. Note that this doesn't fix the window content not being updated during a window resize/move beacuse thos have their own message loop which doesn't return early when it's time to paint. * [rcore][win32] fallback to finding functions from opengl32.dll * [rcore][win32] fixes from review/for gcc * [rcore][win32] incorporate style conventions * [rcore][win32] workaround unused function error SetupFramebuffer * [rcore][win32] re-enable sanitize flags check for MSAA_4X * [rcore][win32] more style changes and remove old DPI cases Added some more missing spaces after conditional statements. Also made unsupported MSAA_4X an assert instead of an abort and also removed dpi-aware cases for older OS's. More changes would be needed to support those OS versions, namely, removing the dependency on shcore. * [rcore][win32] fixes for compling with w64devkit without -DUNICODE * Update build.zig * Update build.zig --------- Co-authored-by: Ray <raysan5@gmail.com>pull/5163/head
