You can't actually write any data to the buffer yet, since we don't have

bjorn c9fe026a66 Fix undefined behavior in arr_free; 
Currently there is a single allocator function used in arr_t.  Its
behavior depends on the values for the pointer and size arguments:

- If pointer is NULL, it should allocate new memory.
- If pointer is non-NULL and size is positive, it should resize memory.
- If size is zero, it should free memory.

All instances of arr_t use realloc for this right now.  The problem
is that realloc's behavior is undefined when the size argument is zero.
On Windows and Linux, realloc will free the pointer, but on macOS this
isn't the case.  This means that arr_t leaks memory on macOS.

It's best to not rely on undefined behavior like this, so let's instead
use a helper function that behaves the way we want.

bjorn b22dbd8f0c Add luax_checku32 and luax_optu32; 
These functions read an unsigned 32 bit integer from the Lua stack
and error if the value is negative or too big.  Currently converting
Lua numbers to integers will silently wrap or invoke undefined behavior
when they are outside of the acceptable range.

For projects that don't want the overhead of type/bounds checks, the
supercharge build option (LOVR_UNCHECKED) can now be used to skip all
type/bounds checks.

bjorn 8462beef00 Fix/improve alpha cutoff; 
The current flag did not work because float shader flags are not
supported.  It was also not very useful because it was per-shader
and did not use the alpha cutoff property of glTF materials.

Instead, let's turn the shader flag into an enable/disable boolean,
and add a scalar material property named "alphacutoff" that gets
read by the glTF importer.

When the alphaCutoff flag is enabled, the material property will be
compared against the pixel's alpha value to decide whether it should
get discarded.

Nevyn Bengtsson 326d275424 don't free window icon before it's used 
It seems to me like that lovrRelease will delete textureData->blob immediately,
which means the windowing system later can't use it because it's already freed.
There's already a free on line 378 which looks more correct.

Also, icon appears flipped if 'flipped' is set to true here on Linux. Is GLFW
inconsistent between linux and windows, or should it indeed be false?

bjorn 4379d25e1c Organization; 2020-01-27 14:02:54 -08:00
Cassie Jones 3e09120173 Compile shaders using source lengths 
The previous implementation relied on glShaderSource inferring source
lengths when the lengths weren't specified. This relies on the sources
being properly null-terminated, however, which isn't the case due to
file loading changes which now use pointer + length. This could cause
intermittent crashes.

Changing this on the shader side meant adding some extra arguments for
passing around shader source lengths. For most of the other cases, where
we're using string literals as the sources, we can just specify -1 as
the length, since OpenGL will calculate the string length for you any
time the length is negative.

bjorn 06fb8b2503 Simplify fill; 
lovr.graphics.fill renders a fullscreen quad, it's convenient because
you don't need to set up a mesh and toggle all the pipeline states.

However, if you are dealing with copying/rendering between stereo
textures, you have to write your own shader for that.  For now.
