GLFW tries to create an OpenGL context by default when creating a
window. This is not necessary when OpenGL is not used. This is an
optimization by skipping to create an OpenGL context if possible.
Apparently, there are some special devices that are recognized as
joysticks by GLFW, even though they are not. Such devices can have
too many 'buttons'. Skip them as a tentative solution.
Updates #1173
isTexture was used to detect context-lost and called every frame.
This was not good for performance.
This change adds a way to notify context-lost from the WebGL
handlers directly, and the package restorable uses it instead of
calling (*Image).isInvalaidated.
Fixes#1175
On Windows, a specified window size might not match with the
actual window size when the size is too big. In this case, Ebiten
could not render the offscreen well and the upper side was cropped.
To avoid this, use the actual window size for the offscreen.
Fixes#1163
Especially in the initial phase before calling Run/RunGame, the
window position is not reliable and then getting the device scale
factor does not make sense based on the window position. Avoid
using the window position, and instead use the glfw.Monitor in
this situation.
Revert "uidriver/glfw: Bug fix: compile error on Linux"
This reverts commit 0a5126f776.
This reverts commit 3e244d7a7c.
Reason: GetMonitor is available only on fullscreen mode
On Windows, the window could be maximized even when the window was
not resizable. This behavior is confusing. Forbid it so that the
behavior will be clearer.
Especially in the initial phase before calling Run/RunGame, the
window position is not reliable and then getting the device scale
factor does not make sense based on the window position. Avoid
using the window position, and instead use the glfw.Monitor.
This change changes the behavior of WindowPosition /
SetWindowPosition. The window position is now a relative position
and the origin position is the left-upper of the current monitor.
Fixes#1115
