[client] egl: add framework for multiple scaling algorithms This commit fixes the issues with the meaning of useNearest being flipped by removing the variable and use enumerations. We define an enumeration EGL_DesktopScaleType to express the type of scaling needed to be performed: no scaling, upscaling, or downscaling. This is updated when either the frame size or the viewport size changes. Previously, we only updated the useNearest when the frame size changes. The desktop shader can now support an enumeration of scaling algorithms, although only nearest and linear are currently implemented. Like before, nearest is used when not scaling or upscaling, and linear is used when downscaling.

[client] egl: add option to set initial scale algorithm The option is egl:scale. The scale algorithm number is displayed on the alert to make it easier to specify the number for the option.

[client] egl: replace monolithic EGLTexture with modular version The way things were handled in EGLTexture is not only very hard to follow, but broken. This change set breaks up EGLTexture into a modular design making it easier to implement the various versions. Note that DMABUF is currently broken and needs to be re-implemented.

[client] all: properly support guest rotation If the guest has it's output rotated (ie, landscape) we must rotate and translate the pointer draw location, as well as all the translations of cursor coordinate spaces based on the rotation, along with any local rotations that may also be applied.
