Sam Lantinga 29f4a5ba0e Add GLES2 shader prologue infrastructure. (by @eloj) 
There is supposedly an OpenGL ES2 target that does not support precision specifiers. However, the existing logic to detect this is currently broken in two ways:

1) There's a typo of the `#ifdef` as `#if`.
2) Checking for `GL_FRAGMENT_PRECISION_HIGH` can not be the correct way to detect this platform. Other targets, including some desktops, will also not have this defined (for various reasons).

Because some of the shader code is missing precision specifiers, and because a default is ONLY provided if `GL_FRAGMENT_PRECISION_HIGH` is set, these other targets break.

Instead of 'hard-coding' the prologue string into shaders in the C source, use our ability to provide a list of strings to `glShaderSource` instead, leaving the determination to run-time.

Sam Lantinga 50c5d23f7d Round coordinates so very small floating point values don't turn into 0x80000000

Ethan Lee a28f426acb render: Only update size/scale/viewport when moving to a new display, rather than all window movement. 
We really only care about DPI changes here, so this both reduces work and also avoids weird cases where viewport state can be corrupted by trivial window events. This doesn't _completely_ get rid of the issue but this is somewhat intentional, since apps will definitely want to do a full reset when changing displays anyhow (otherwise DPI/adapter changes will screw things up, and that's out of our control as long as both window size and drawable size are exposed at the same time.

Note that OpenGL still captures window events because of weird platform-specific issues like macOS and viewport stretching!

Fixes #5949
