In OpenTK 1.1, GraphicsMode queries the platform for a mode id lazily.
By delaying VisualInfo selection until the GraphicsContext is constructed
we ensure that a concrete GraphicsMode is selected and ready for use.
SDL2 does not support changing display resolutions independently of an
SDL window. As a workaround, if the user uses ChangeResolution and then
makes a GameWindow fullscreen, we use old-style SDL fullscreen which
changes the resolution. If the user makes a GameWindow fullscreen
without calling ChangeResolution first, we use the new
fullscreen-desktop mode to match the other OpenTK backends.
It makes sense to generate convenience overloads for each relevant
wrapper function, instead of each entry point. This way, we generate
convenience overloads for every wrapper in overrides.xml (even wrappers
for background compatibility), which would otherwise be ignored.
When a function parameter matches a strongly-typed enum, the parameter
type is explicitly set to that enum. This fixes issues with function
parameters referring to enums whose names change after translation.
WS_CLIPCHILDREN and WS_CLIPSIBLINGS appear to cause flickering on
specific video cards. OpenGL appears to work correctly without these, so
we'll disable them to return to OpenTK 1.0 behavior.
It is now possible to indicate that an application is not DPI-aware. In
that case, OpenTK will let the operating system handle DPI scaling. This
results in worse visuals (pixel doubling) but allows non DPI-aware
applications to continue working.
When we enter the modal resize loop on Windows with ClipCursor set, we
cause a feedback loop where every resize causes the cursor to move and
every move causes a new resize. To fix this, we need to ungrab the
cursor when we are enter the modal loop.
