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 bfb73f0c19 Improve Sound:getFrames Blob error message; 
Probably need a generic "out of range" template, but this makes things
better for now.

Josip Miskovic 110333fce7 Fix gamma/linear conversion of a RGB table 
Correcting the order of stack operations to fetch RGB components from
the table and to put in conversion the results.

Before the fix these two calls produced different results:
`lovr.math.gammaToLinear(  0.1, 0.2, 0.3  )`
`lovr.math.gammaToLinear( {0.1, 0.2, 0.3} )`

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.

bjorn 9ff00ae789 tup: use d8 instead of dx; 2021-12-07 18:20:03 +02:00
Nevyn Bengtsson 06dd81f6d7 Use d8 instead of dx 
dx was deprecated years ago, and d8 replaces it. dx is
removed in build-tools 31, so it's best not to depend on it.

In addition, d8 now supports Java 11 (class version 55), which
is required to use the javac bundled with Android Studio.

bjorn 255ecbb4d8 Fix stencil color mask; 
- When calling lovr.graphics.stencil, the color mask is initially
  disabled, and gets restored to its initial state afterwards.
- However, when it's restored, it uses lovrGraphicsSetColorMask, which
  just sets shadow state that doesn't make it all the way to GL until
  another draw is done.
- The consequence of this is that if you call .stencil and then don't do
  a draw, any clears that happen will use the old (disabled) color mask,
  preventing the color buffer from being cleared.
- The solution here is to lower the color mask change down into opengl.c
  where it can directly hit OpenGL.

Josip Miskovic 015a2ed69c Accept number values in Vec2/3/4 operations 
Vector methods are extended to receive vectors as individual numbers
for each of x,y,z,w component. The vector objects are still supported
as well.

Previously only single value scalar was supported. This change maintains
backward compatibility.

```
v = vec3():add( 1, 2, 3 )          -- both do the same
v = vec3():add( vec3(1, 2, 3) )    _/

v = vec4():mul( 2 )            -- x component is a default for y, z
v = vec4():mul( 2, 2, 2, 2 )   _/

v = vec2():lerp( 2, 2, 0.5 )        -- in lerp, dot, cross, distance
v = vec2():lerp( vec2(2, 2), 0.5 )  _/   all components are mandatory
